Abstract
OBJECTIVE In this study, demographic, clinical, and laboratory data of patients aged 65 and over who are followed on mechanical ventilators due to COVID-19 in intensive care clinics will be useful in terms of strategies to be developed in the fight against COVID-19 and other infectious agents. PATIENTS AND METHODS Our study included 299 patients aged 65 years and older, who were not chronically ill, and who were followed up on mechanical ventilators due to COVID-19 in intensive care clinics in the period between 2020 and 2022. Our study was designed as a retrospective cross-sectional study. The demographic characteristics of the patients included in the study, their complaints during hospitalization, the time between the beginning of the complaint and the admission to the hospital, the vital signs at the time of admission to the hospital, the lung computed tomography findings during hospitalization, and the treatments given were examined. RESULTS 55.9% of all patients were males, and the mean age was 75.45±7.47 years. While there was no significant difference in terms of mean age between the groups of patients with/without a higher risk of mortality, there was a significant difference in gender (p=0.025). There was a statistically significant difference between the COVID-19 intensive care (p=0.001) and renal failure (p=0.014) and mortality groups. The mean nutric score, Procalcitonin (PCT), Lactate Dehydrogenase (LDH), Blood Urea Nitrogen (BUN), Phosphorus, and lactate values, which are important parameters, were statistically higher in the group with a higher risk of mortality (p<0.001). In addition, there was a statistically significant difference in terms of sepsis, neuromuscular blocker (Nmb), vasopressor, and intubation between the groups of patients with/without a higher risk of mortality (p<0.001). In the group with high mortality, 34.2% (n=55) had plasmapheresis treatment, and 14.2% had hemodiafiltration treatment (p<0.001). According to the results of the multivariate logistic regression model in determining the factors associated with a higher risk of mortality, those who were males (p=0.001), those with kidney failure (p<0.001), those with organ failure (p=0.006), increased in alanine aminotransferase (ALT) values (p=0.019), those with sedation (p=0.001) and those with vasopressors (p<0.001) were found to have an increased risk of mortality. CONCLUSIONS We think that our study is valuable in terms of determining the most appropriate treatment strategies by following the patients in terms of parameters that are significant in the findings during their follow-up period in the Intensive Care Unit.

The Anti-Inflammatory and Antioxidant Effects of Propofol and Sevoflurane in Children With Cyanotic Congenital Heart Disease. J Cardiothorac Vasc Anesth 2023; 37:65-72. [PMID: 36307353 DOI: 10.1053/j.jvca.2022.09.094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 08/25/2022] [Accepted: 09/24/2022] [Indexed: 12/30/2022]
Abstract
OBJECTIVE The authors aimed to compare the anti-inflammatory and antioxidant effects of propofol and sevoflurane in children with cyanotic congenital heart disease (CCHD) undergoing cardiac surgery with cardiopulmonary bypass. DESIGN Prospective, randomized, double-blind study. SETTING Single center, university hospital. PARTICIPANTS Children ages 1-10 years with CCHD undergoing elective cardiac surgery with cardiopulmonary bypass. INTERVENTIONS Children were randomized to receive general anesthesia with either sevoflurane (group S) or propofol (group P). Systemic inflammatory response syndrome (SIRS) occurrence was assessed at the end of the surgery and at the sixth, 12th, and 24th postoperative hours. Blood samples were obtained at 4 times: after anesthesia induction (T0), after release of the aortic cross-clamp (T1), at the end of the surgery (T2), and at the postoperative 24th hour (T3). The serum levels of interleukin 6 and tumor necrosis factor alpha, and the total antioxidant status (TAS) and total oxidant status, were analyzed. RESULTS SIRS was more common in group S than in group P at all times (p = 0.020, p = 0.036, p = 0.004, p = 0.008). There were no significant differences between the groups in the mean tumor necrosis factor alpha and interleukin 6 levels at any time. The TAS level at T2 was higher in group P than group S (p = 0.036). The serum TAS level increased at T2 compared with T0 in group P, but it decreased in group S (p = 0.041). CONCLUSION The results showed that propofol provided a greater antioxidant effect and reduced SIRS postoperatively more than sevoflurane in children with CCHD undergoing cardiac surgery.

Bilateral erector spinae plane blocks in children undergoing cardiac surgery: A randomized, controlled study. J Clin Anesth 2022; 80:110797. [PMID: 35489304 DOI: 10.1016/j.jclinane.2022.110797] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 01/31/2022] [Accepted: 03/27/2022] [Indexed: 12/12/2022]
Abstract
STUDY OBJECTIVE We aimed to test the hypothesis that erector spinae plane block (ESPB) provides efficient analgesia and reduces postoperative morphine consumption in children undergoing cardiac surgery with median sternotomy. DESIGN A prospective, blinded, randomized, controlled study. SETTING A tertiary university hospital, operating room and intensive care unit. PATIENTS Forty children aged 2-10 years, who underwent cardiac surgery with median sternotomy. The patients were randomly divided into the block group (Group B) and the control group (Group C). INTERVENTIONS Group B (n = 20) were treated with ultrasound-guided bilateral ESPB at the level of the T4-T5 transverse process, whereas no block was administered in Group C (n = 20). In all children, intravenous morphine at 0.05 mg/kg was used whenever the modified objective pain score (MOPS) ≥4 for postoperative analgesia. MEASUREMENTS The MOPS and Ramsay sedation score (RSS) were assessed at 0, 1, 2, 4, 6, 8, 10, 12, 16, 20 and 24 h postoperatively. Total morphine consumption at 24 h, extubation time and length of intensive care unit (ICU) stay was also evaluated and recorded. MAIN RESULTS Bilateral ESPB significantly decreased the consumption of morphine in the first 24 h, postoperatively. During the postoperative 24-h follow-up, 11 children in Group C requested morphine and the cumulative dose of morphine was 0.83 ± 0.91 mg, while 4 children in Group B requested morphine and the cumulative dose of morphine was 0.26 ± 0.59 mg (p = 0.043). There was no significant difference between Groups B and C in terms of MOPS and RSS values, extubation time or length of ICU stay. CONCLUSION Ultrasound-guided bilateral ESPB with bupivacaine provides efficient postoperative analgesia and reduces postoperative morphine consumption at 24 h in children undergoing cardiac surgery.

Vasopressors for the Treatment and Prophylaxis of Spinal Induced Hypotension during Caesarean Section. Turk J Anaesthesiol Reanim 2021; 49:3-10. [PMID: 33718899 PMCID: PMC7932705 DOI: 10.5152/tjar.2020.70] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Accepted: 12/23/2019] [Indexed: 11/24/2022] Open
Abstract
Vasopressors have currently become the mainstay therapy for the management of spinal-induced hypotension (SIH) as the major mechanism of hypotension after spinal anaesthesia is the loss of arteriolar tone produced by sympathetic block. Vasopressors for the prophylaxis and treatment of SIH have been the subject of a significant amount of research, yet remain an attractive and important clinical problem. This review will highlight controversies and recent research on the use of vasopressors for both prophylaxis and treatment of SIH. For decades, ephedrine was considered to be the best vasopressor for the management of maternal hypotension. However, its use has been reported to be associated with a 5-fold increased risk of foetal acidosis than phenylephrine. At present, phenylephrine is the vasopressor of choice for preventing and treating SIH at caesarean section. However, its use is often associated with a decreased heart rate and low cardiac output state owing to the lack of β-mimetic activity. Norepinephrine has been introduced as an alternative vasopressor for preventing and treating SIH because of its additional β-mimetic activity. However before its routine clinical use, a further series of studies are needed to establish its efficacy and safety for both the mother and foetus.

Abstract
BACKGROUND AND OBJECTIVES Limited data are present on safety and efficiency of epinephrine for the prophylaxis and treatment of spinal-hypotension. This study was conducted to compare the effect of epinephrine with norepinephrine and phenylephrine on the treatment of spinal-hypotension and ephedrine requirement during cesarean delivery. METHODS One hundred and sixty parturients with uncomplicated pregnancies undergoing elective cesarean delivery under spinal anesthesia were recruited. They were allocated randomly to receive norepinephrine 5 μg.mL-1 (n=40), epinephrine 5 μg.mL-1 (n=40), phenylephrine 100 μg.mL-1 (n=40) or 0.9% saline infusions (n=40) immediately after induction of spinal anesthesia. Whenever systolic blood pressure drops to less than 80% of baseline, 5 mg of iv ephedrine was administered as rescue vasopressor. The incidence of hypotension, total number of hypotension episodes, the number of patients requiring ephedrine, the mean amount of ephedrine consumption and side effects were recorded. RESULTS There was no statistically significant difference in incidence of maternal hypotension between groups. The number of patients requiring ephedrine was significantly greater in group saline than in group phenylephrine (p <0.001). However, it was similar between phenylephrine, norepinephrine, and epinephrine groups. The mean ephedrine consumption was significantly higher in group saline than in norepinephrine, epinephrine, phenylephrine groups (p=0.001). CONCLUSION There is no statistically significant difference in incidence of hypotension and ephedrine consumption during spinal anesthesia for cesarean delivery with the use of epinephrine when compared to norepinephrine or phenylephrine. Epinephrine can be considered as an alternative agent for management of spinal hypotension.

Abstract
The analgesic benefit of melatonin and vitamin C as primary or adjuvant agents has been reported in various studies; however, their analgesic effects in the treatment of postoperative pain remain unclear. Thus, we aimed to evaluate the effect of single preoperative dose of oral melatonin or vitamin C administration on postoperative analgesia. In this study, we recruited 165 adult patients undergoing elective major abdominal surgery under general anesthesia. Patients were randomly divided into three equal (n = 55) groups. One hour before surgery, patients received orally melatonin (6 mg) in group M, vitamin C (2 g) in group C, or a placebo tablet in group P. Pain, sedation, patient satisfaction, total morphine consumption from a patient-controlled analgesia device, supplemental analgesic requirement, and the incidence of nausea and vomiting were recorded throughout 24 h after surgery. The mean pain score and total morphine consumption were found significantly lower in both M and C groups compared with group P (p < 0.001). There were no significant differences between group M and C with respect to pain scores (p = 0.117) and total morphine consumption (p = 0.090). Patients requested less supplemental analgesic and experienced less nausea and vomiting in groups M and C compared with group P. In conclusion, preoperative oral administration of 6 mg melatonin or 2 g vitamin C led to a reduction in pain scores, total morphine consumption, supplemental analgesic requirement, and the incidence of nausea and vomiting compared with placebo.

Abstract
Objective The effect of sugammadex on consciousness is not yet fully understood. This prospective, randomized, double-blind, multicenter study was performed to compare the effects of intravenous (IV) sugammadex and neostigmine + atropine reversals on time-to-consciousness during intraoperative wake-up tests in patients undergoing spinal surgery. Subjects and Methods A total of 66 American Society of Anesthesiologists I-II patients aged 10-25 years undergoing spinal surgery were recruited. In all patients, bispectral index (BIS), motor-evoked potential (MEP), somatosensory-evoked potentials (SSEP), and train-of-four (TOF) scores were monitored. Patients received the same total IV anesthesia protocol with a propofol-remifentanil mixture. Patients were randomly allocated into two groups. During wake-up test, when the TOF count reached 2 (T2), either sugammadex 2 mg.kg-1 in group S or neostigmine 0.04 mg.kg-1 + atropine 0.01 mg.kg-1 in group N were administered. BIS90, SSEP90, MEP90 was recorded when TOF ratio reached 90, whereas time-to-consciousness (Timecons) was recorded when the patient responded to verbal commands. Results BIS90 (77.4 ± 4.7, 74.8 ± 3.7), SSEP90(36 ± 9.9, 29.7 ± 8.5), and MEP90 (465.3 ± 34.8, 431.3 ± 28.2) values were significantly greater in group S than in group N (P < 0.05 for each variables). Timecons was significantly shorter with sugammadex than with the neostigmine + atropine combination (P < 0.05). Conclusion Using IV sugammadex 2 mg.kg-1 reversal provides faster responses to verbal commands than neostigmine-atropine combination during the intraoperative wake-up test in patients undergoing spinal surgery because the time to consciousness was significantly shorter. This difference was thought to be related with faster return of neuromuscular transmission because the TOF ratio was >0.9 well before return of consciousness in both groups.

Abstract
Objective Abnormal placental invasion (API) is defined as an abnormal adherence of the placenta to the underlying uterine wall. Undiagnosed API may result in catastrophic maternal haemorrhage during delivery. In the present retrospective analysis, anaesthetic and surgical records were evaluated in patients with API who had undergone caesarean delivery (CD). Methods Clinical records of 89 patients with API who had undergone CD were retrospectively reviewed in our clinic between April 2010 and February 2017. Results Amongst the patients, 87 (97.8%) had a history of previous CD and 68 (76.4%) had placenta previa. In regression analysis, weak positive correlation was found between an increase in packed red blood cell (PRBC) (r=0.420, p=0.001) and fresh frozen plasma (FFP) (r=0.476, p=0.022) transfusions and time of hospital stay. PRBC and FFP consumptions were significantly greater in intensive care unit (ICU) patients than in non-ICU patients (p<0.001). ICU requirement were significantly greater in patients who had more than average crystalloid (p=0.004) and colloid (p<0.001) infusions. Elective CD was performed in 81 (91%) patients and emergency CD in 8 (9%). PRBC transfusions were 7±4.3 U in patients undergoing emergency CD and 3.85±3 U in patients undergoing elective CD (p=0.034). The number of patients requiring care in ICU was 4 (50%), who underwent emergency CD and 12 (14%) who underwent elective CD, (p=0.032). Conclusion It is crucial that the anaesthesiologist should be familiar with the risk factors and diagnosis of API because of the potential risk of massive haemorrhage. Multidisciplinary approach with surgery and blood bank decreases the amount of bleeding, blood transfusion requirement, ICU and hospital stay in patients with API.

Abstract
Objective The study was designed to compare the postoperative analgesic efficacy of epidural tramadol or epidural morphine as adjuvant to levobupivacaine in major abdominal surgery. Methods Patients in ASA I-II group aged between 18 and 65 years were included in study. Epidural catheter was introduced. Patients were randomised into three groups to receive levobupivacaine (Group L), levobupivacaine+morphine (Group LM) and levobupivacaine+tramadol (Group LT). General anaesthesia was administered to all patients. The solution intended for Group L contained 25 mg 0.5% levobupivacaine+15 mL saline, that for Group LM contained 25 mg 0.5% levobupivacaine+14.5 mL salin+100 μg morphine and that for Group LT contained 25 mg 0.5% levobupivacaine+13 mL salin+100 mg tramadol, which was administered via epidural catheter as loading dose 30 min before the end of the operation. Patient-controlled analgesia device was connected to the epidural catheter to provide postoperative analgesia. Bolus dose was adjusted to 12 mg levobupivacaine in Group L, 12 mg levobupivacaine +1.2 mg morphine in Group LM and 12 mg levobupivacaine+12 mg tramadol in Group LT. Lock-out period was adjusted to 15 min in three groups. Quality of analgesia was evaluated using Visual Analogue Scale; administered and demand doses of levobupivacaine, morphine and tramadol were compared at 30 min, 1, 2, 6, 12 and 24 h postoperatively. Results Visual Analogue Scale scores were significantly higher in Group L than Groups LM and LT. Nausea and vomiting observed in Group L were lesser than those in Groups LM and LT. Conclusion Continuous epidural analgesia using levobupivacaine combined with morphine or tramadol is an effective method for managing postoperative analgesia in major abdominal surgery.

Abstract
Background and objectives Pediatric patients frequently require deep sedation or general anesthesia for colonoscopy. This study was designed to compare the sedative efficacy of remifentanil–ketamine combination with propofol–ketamine combination in children undergoing colonoscopy. Methods Seventy patients, between 2 and 16 years of age, scheduled for diagnostic colonoscopy were randomly allocated into two groups. Remifentanil–ketamine group received intravenous ketamine 2 mg.kg−1 and remifentanil 0.25 μg.kg−1 combination, followed by 0.1 μg.kg−1.min−1 remifentanil infusion. Propofol–ketamine group received intravenous propofol 1 and 2 mg.kg−1 ketamine combination, followed by 1 mg.kg−1.h−1 propofol infusion. In the case of children discomfort (cry, movement, and cough), remifentanil 0.1 μg.kg−1 in the remifentanil–ketamine group or propofol 0.5 mg.kg−1 in the propofol–ketamine group were administered to improve children discomfort. Despite the therapy given above, if children still experience discomfort, 1 mg.kg−1 of ketamine was administered as a rescue drug, regardless of the group. Ramsay sedation score, hemodynamic variables, drug requirements, gastroenterologists’ satisfaction, colonoscopy duration, recovery time, and side effects were recorded throughout the procedure and the recovery period. Results The percentage of patients with a Ramsay sedation score of 4 or higher during the procedure was 73.5 and 37.1% in remifentanil–ketamine and propofol–ketamine groups, respectively (p = 0.02). Systolic and diastolic blood pressure variables were significantly higher only after induction in the remifentanil–ketamine group than in the propofol–ketamine group (p = 0.015). Conclusion Coadministration of ketamine with either remifentanil or propofol effectively and safely provides sedation and analgesia in children undergoing colonoscopy. Sedation scores were significantly better in remifentanil–ketamine group than in propofol–ketamine group.

Abstract
Background/aim: We aimed to investigate the effect of long-term use of dexamethasone and prednisolone on the reversal effect of sugammadex. Materials and methods: TTwenty-four male Wistar albino rats were divided into three groups. Dexamethasone (600 µg/kg) was given to group D, prednisolone (10 mg/kg) was given to group P, and an equivalent volume of saline per day was administered intraperitoneally to group S for 14 days, respectively. The left hemidiaphragm with attached phrenic nerve was maintained in Krebs solution. Sugammadex (30 µmol/L) was applied while rocuronium (10 µmol/L) was present in an organ bath and a single twitch was obtained. The right hemidiaphragm was used for both adult ( ε-subunit) and fetal nicotinic acetylcholine receptor (AChR) ( ε-subunit) determination using polymerase chain reaction. Results: All animals lost weight, except group S. The mean baseline single-twitch tension was lower in both group D (14.4 ± 1.7 g) and group P (12.68 ± 0.05 g) than group S (16.8 ± 0.5 g) (P < 0.001). When sugammadex was added to the organ bath while rocuronium was present, the single twitch was measured to be lower in both group D (11.7 ± 0.7 g) and group P (11.5 ± 0.78 g) than group S (16.5 ± 0.24 g) (P < 0.001). Ɣ-AChR expression was higher in both dexamethasone and prednisolone than in saline. Conclusion: Long-term medication with dexamethasone and prednisolone caused muscle weakness, resistance to neuromuscular blockers, and upregulation of immature Ɣ-AChR and reduced the neuromuscular reversal effect of sugammadex.

[PMID: 30205906 DOI: 10.1016/j.bjan.2018.06.015] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2017] [Revised: 04/26/2018] [Accepted: 06/22/2018] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Pediatric patients frequently require deep sedation or general anesthesia for colonoscopy. This study was designed to compare the sedative efficacy of remifentanil-ketamine combination with propofol-ketamine combination in children undergoing colonoscopy. METHODS Seventy patients, between 2 and 16 years of age, scheduled for diagnostic colonoscopy were randomly allocated into two groups. Remifentanil-ketamine group received intravenous ketamine 2mg.kg-1 and remifentanil 0.25μg.kg-1 combination, followed by 0.1μg.kg-1.min-1 remifentanil infusion. Propofol-ketamine group received intravenous propofol 1 and 2mg.kg-1 ketamine combination, followed by 1mg.kg-1.h-1 propofol infusion. In the case of children discomfort (cry, movement, and cough), remifentanil 0.1μg.kg-1 in the remifentanil-ketamine group or propofol 0.5mg.kg-1 in the propofol-ketamine group were administered to improve children discomfort. Despite the therapy given above, if children still experience discomfort, 1mg.kg-1 of ketamine was administered as a rescue drug, regardless of the group. Ramsay sedation score, hemodynamic variables, drug requirements, gastroenterologists' satisfaction, colonoscopy duration, recovery time, and side effects were recorded throughout the procedure and the recovery period. RESULTS The percentage of patients with a Ramsay sedation score of 4 or higher during the procedure was 73.5 and 37.1% in remifentanil-ketamine and propofol-ketamine groups, respectively (p=0.02). Systolic and diastolic blood pressure variables were significantly higher only after induction in the remifentanil-ketamine group than in the propofol-ketamine group (p=0.015). CONCLUSION Coadministration of ketamine with either remifentanil or propofol effectively and safely provides sedation and analgesia in children undergoing colonoscopy. Sedation scores were significantly better in remifentanil-ketamine group than in propofol-ketamine group.

Abstract
OBJECTIVES In this study, we aimed to determine the effect of remifentanil administration prior to slow and fast rocuronium infusion on hemodynamic changes and rocuronium injection pain in pediatric patients. METHODS In total, 120 5-15-year-old ASA score I/II pediatric patients were included in the study. Group A: slow rocuronium injection-saline; group B: slow rocuronium injection (0.6 mg/kg IV)-remifentanyl; group C: fast rocuronium injection-saline; and group D: fast rocuronium injection-remifentanyl. Withdrawal movement after rocuronium injection was recorded based on a 3-point response to withdrawal score. Hemodynamic parameters were recorded. RESULTS One minute after rocuronium injection, HR values were found to be lower in remifentanil groups (p: 0.0001; 101.4±22.1, p: 0.003; 99.8±18.3 in group B and D, respectively) compared with those in placebo groups (p: 0.025; 107.4±21.7, p: 0.012; 114.0±16.4 in group A and C, respectively). With respect to the response to withdrawal scores, unresponsiveness rates were the highest in group B (66.7%) and group D (70%). The number of non-responder patients was 9 in saline-administered groups (group A and C), whereas it was 20 and 21 in remifentanil-administered groups (group B and D, respectively). Generalized responses were observed predominantly in groups A (20%) and C (20%). Generalized responses were highest in groups A (20%, n=6) and C (20%, n=6). CONCLUSION There was no impact of infusion speed on rocuronium injection pain in pediatric cases, whereas it is concluded that remifentanil administration prior to rocuronium injection considerably reduced rocuronium injection pain regardless of injection speed and without serious hemodynamic changes.

Abstract
OBJECTIVE To determine the blood sevoflurane and desflurane concentrations during one-lung ventilation (OLV). DESIGN Randomized, single-blind study. SETTING Single university hospital. PARTICIPANTS The study comprised 24 patients, 35 to 70 years old who were scheduled for either a major abdominal surgery or thoracotomy. INTERVENTIONS The patients were divided into the following 4 groups: sevoflurane two-lung ventilation (TLV), sevoflurane OLV, desflurane TLV, and desflurane OLV. Vaporizers were set at 1.5% sevoflurane or 6% desflurane. MEASUREMENTS AND MAIN RESULTS In the TLV groups, blood samples were taken in 10-minute intervals starting 40 minutes after the start of TLV (T1-T9) for blood gas analysis and gas chromatography. In the OLV groups, the first sample was collected at 40 minutes of TLV (T1), and other samples were collected in 10-minute intervals from the start of OLV (T2-T9). Saturation of peripheral oxygen (SpO2), hemodynamic variables, and inspired and end-tidal volatiles were recorded. The fraction uptake of the volatile agents (F) was calculated for each patient at the same time points. The mean arterial sevoflurane concentration in the sevoflurane OLV group at T1 decreased from 40.7 ± 4.4 to 30.2 ± 2.5 µg/mL at T3 (p = 0.014, 26% decrease). In the OLV desflurane group, the mean arterial desflurane concentration at T1 declined from 224.6 ± 44.8 to 159.8 ± 32 µg/mL at T3 (p=0.018, 29% decrease). However, the reduction of sevoflurane concentration compared with that of desflurane at T3 was not statistically significant (p = 0.31). In addition, the fraction uptake of the volatile agents values significantly increased at the start of OLV (p = 0.001). CONCLUSION An OLV procedure causes a decrease in the both arterial and venous blood concentrations of sevoflurane and desflurane. This reduction is believed to be due to ventilation-perfusion mismatch.

Does prophylactic ondansetron reduce norepinephrine consumption in patients undergoing cesarean section with spinal anesthesia? J Anesth 2017; 32:90-97. [PMID: 29243058 DOI: 10.1007/s00540-017-2436-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2017] [Accepted: 11/28/2017] [Indexed: 11/24/2022]
Abstract
PURPOSE Spinal anesthesia-induced hypotension (SAIH) during cesarean delivery is not rare and frequently leads to materno-fetal discrepancy and collapse. More recently, norepinephrine has been proposed for the prevention and treatment of SAIH with fewer tendencies to decrease heart rate and cardiac output. Ondansetron has been reported to reduce the incidence of SAIH in patients undergoing cesarean section. The aim of the present study was to assess the effect of prophylactic ondansetron on the incidence of SAIH, norepinephrine consumption, and adverse effects. METHODS We recruited 108 parturients with uncomplicated pregnancies undergoing elective cesarean delivery under spinal anesthesia. The parturients were divided into two groups randomly. The first group (n = 54) received 8 mg ondansetron IV (group O) and the second group (n = 54) received the same volume (4 ml) of saline (group S), 5 min before spinal anesthesia. The incidence of hypotension, cumulative episodes of hypotension, total norepinephrine consumption, and adverse effects were recorded. RESULTS There was no significant difference between the two groups in demographic data, parturient characteristics, and duration of surgery. No significant difference was found in the incidence of hypotension in the saline and ondansetron groups (p = 0.767). However, the cumulative episodes of hypotension and norepinephrine consumptions were significantly greater in group S than in group O (p = 0.009) (p = 0.009). There was also no significant difference in the incidence of adverse effects between the two groups. CONCLUSION Eight milligrams of intravenous ondansetron given 5 min before spinal anesthesia attenuated but did not prevent spinal anesthesia-induced hypotension in parturients undergoing elective cesarean delivery.

Abstract
BACKGROUND Dexamethasone has been shown to cause inhibition of sugammadex reversal in functionally innervated human muscle cells. In this prospective, double-blind, randomized, controlled study, we evaluated the effect of dexamethasone on the reversal time of sugammadex in children undergoing tonsillectomy and/or adenoidectomy. METHODS We recruited 60 patients with ASA physical status I to II, between the ages of 3 and 8 years, scheduled for elective tonsillectomy and/or adenoidectomy. After the induction of anesthesia, patients in group D received IV dexamethasone at a dose of 0.5 mg/kg within a total volume of 5 mL saline, whereas patients in group S received only 5 mL IV saline as the control group. At the end of surgery, all patients were given a single bolus dose (2 mg/kg) of sugammadex at reappearance of T2. Demographic data, hemodynamic variables, time to recovery (a train-of-four ratio of 0.9), time to tracheal extubation, and adverse effects were recorded. RESULTS There was no statistical significance between 2 groups in time to recovery and time to extubation. Time to recovery was 97.7 ± 23.9 seconds in group D and 91.1 ± 39.5 seconds in group S (P = 0.436; 95% confidence interval, -10.3 to 23.5). Time to extubation was 127.9 ± 23.2 seconds and 123.8 ± 38.7 seconds in group D and in group S, respectively (P = 0.612; 95% confidence interval, -11.9 to 20.05). CONCLUSIONS IV dexamethasone, given after induction of anesthesia, at a dose of 0.5 mg/kg, does not substantively affect the reversal time of sugammadex in pediatric patients undergoing adenoidectomy and/or tonsillectomy.

Abstract
Brugada Syndrome was first described in 1992 by Pedro Brugada as a genetic syndrome that is characterized by ventricular arrhythmias that may result in sudden cardiac arrest. In particular, a right bundle branch block and ST segment elevation in the right precordial leads are observed. Many perioperative pharmalogical and physiological factors can trigger malignant arrhythmias. Although it is a rare condition, the anaesthestic management of Brugada syndrome is important because of the potentially fatal complications. Many anaesthetics have been administered during the operation of patients with Brugada Syndrome. The use of sugammadex instead of the anaesthetic management of patients with Brugada syndrome is discussed in this study.

Abstract
OBJECTIVE We aimed to evaluate the effect of anaesthesia with thiopental (4 mg kg(-1)), ketamine (1 mg kg(-1)) and ketamine-thiopental (1 mg kg(-1) and 4 mg kg(-1), respectively) combination during electroconvulsive therapy (ECT) on the Hamilton Depression Rating Scale (HDRS) and Hamilton Anxiety Rating Scale (HAM-A) and haemodynamic variables in patients with resistant major depression. METHODS Patients with HDRS scores above 17 were included. The patients were randomly divided into three groups according to the anaesthesia used. Group 1 was given thiopental (4 mg kg(-1)), Group 2 was given ketamine (1 mg kg(-1)) and Group 3 was given ketamine (1 mg kg(-1)) and thiopental (4 mg kg(-1)). Succinylcholine (1 mg kg(-1)) was administered in all patients for muscle relaxation. HDRS and HAM-A scores were evaluated before ECT, after 3, 6. ECT and after the final ECT. Systolic and diastolic blood pressures, heart rates and oxygen saturations were recorded before and after anaesthesia induction and after the ECT procedure. Seizure duration was recorded. RESULTS Fifty-eight patients were included in the study. Thirty (52%) patients were male and 28 (48%) were female. The mean age was 42.7±15.8 years in Group 1, 44.8±11 years in Group 2 and 38.6±6.8 years in Group 3. In all groups, HDRS scores were reduced compared with the baseline values. There was no statistical significant difference between the groups regarding HDRS scores. HAM-A scores were higher in Group 2 and Group 3. Systolic and diastolic blood pressures and heart rate values were lower in Group 1 and the difference was statistically significant. CONCLUSION In this study, anaesthesia induced with thiopental, ketamine and thiopental-ketamine combination was observed to not result in a difference in ECT for patients with treatment-resistant depression. Ketamine at a dose of 1 mg kg(-1) given just before ECT did not enhance the antidepressant effect of ECT; however, anxiety scores were increased with ketamine application.

Abstract
OBJECTIVE This study aimed to evaluate the effects of ultrasound-guided rectus sheath block in gynaecological surgery with Pfannenstiel incision. METHODS After the approval of the ethics committee and the patients' consent, 75 ASA I-II patients who were aged between 20 and 70 years and scheduled for a gynaecological surgery with Pfannenstiel incision were included in this study. After induction of general anaesthesia, patients were randomly divided into three groups. In Group UR patients (n=25), ultrasound-guided rectus sheath block with 0.25% levobupivacaine (0.2 mL kg(-1)) was performed. In Group SR patients (n=25), surgical rectus sheath block with 0.25% levobupivacaine (0.2 mL kg(-1)) was applied. In Group T (n=25) patients, tramadol (2 mg kg(-1)) was intravenously administered 30 min before the end of surgery. Patient-controlled analgesia device was established for postoperative pain relief in all groups. Haemodynamic data and inspired sevoflurane concentration were recorded during the operation. Pain scores, total tramadol consumption, supplemental analgesic requirement and side effects were postoperatively evaluated. RESULTS Demographic characteristics, duration of surgery and haemodynamic parameters were similar between the groups. Inspired sevoflurane concentration (%) and VAS scores were significantly lower in Group UR than those in Groups SR and T. Total tramadol consumption was significantly lower in Groups UR and SR than that in Group T. There was no significant difference in the incidence of side effects. CONCLUSION This study demonstrates that ultrasound-guided rectus sheath block helps to provide the effective analgesia without any side effects compared with surgical rectus sheath block and intravenous tramadol for gynaecological surgery with Pfannenstiel incision.

Abstract
Vitamin D is a vitamin not only associated with calcium-phosphorus metabolism but also affects many organ systems. Because of its effect on the immune system in recent years, it has attracted much attention. Vitamin D deficiency is a clinical condition that can be widely observed in the society. Thus, patients with vitamin D deficiency are often seen in anaesthesia practice. In the absence of vitamin D, prolongation of intensive care unit stay, increase in mortality and morbidity and also association of chronic diseases further increase the importance of vitamin D deficiency. The results obtained from studies have led to the question of whether poor surgical outcome is associated with vitamin D deficiency. We assessed the vitamin D deficiency and its negative consequences for the anaesthesiologist.

Abstract
OBJECTIVES This randomized double-blind controlled trial examined the effects of fentanyl and morphine, alone and in combination, as adjuncts to spinal anesthesia for elective cesarean section. METHODS Sixty women undergoing elective cesarean section, with spinal anesthesia using 0.5% hyperbaric bupivacaine, were randomly allocated to receive morphine 0.2 mg, fentanyl 25 µg, or fentanyl 12.5 µg plus morphine 0.1 mg, intrathecally. The start of spinal block, the time to T10 level, the highest sensorial and motor block level, time to regression of sensory block to T10, time to resolution of motor block, surgical characteristics, maternal side effects, Apgar and NACS scores, umbilical blood gas evaluations, and time to first analgesic requirement were recorded. RESULTS No patient experienced pain during the intraoperative period. The degree and time of sensorial and motor block were similar in both groups, and there was no difference in time to T10 level and time to reversal of motor block. The difference in time to first postoperative analgesic requirement was statistically significant. There was no difference between groups in postoperative side effects. There were no neonatal differences in Apgar and NACS scores or umbilical blood gas evaluations. CONCLUSION The quality of postoperative analgesia with morphine, when used alone, was found to be superior to that with fentanyl. The combination of opioids offered no advantages over morphine alone.
