Postoperative Vomiting Following Laparoscopic Cholecystectomy Is Associated with Intraoperative Fluid Administration: A Retrospective Cohort Study

Comparison of Nausea and Vomiting Incidence After Laparoscopic Cholecystectomy With Pretreatment With Haloperidol and Ondansetron: A Randomization Clinical Trial Study

OBJECTIVE

Nausea and vomiting after surgery are the most common complications. Therefore, we performed this study to compare the effect of ondansetron and haloperidol on nausea and vomiting after laparoscopic cholecystectomy.

PATIENTS AND METHODS

In this randomized clinical trial, 60 patients candidates for elective laparoscopic cholecystectomy were allocated to haloperidol (0.05 mg/kg, n = 30) and ondansetron (0.15 mg/kg, n = 30) groups. An Ocular Analog Scale was used to assess postoperative nausea and vomiting. Every 15 minutes in the recovery room, heart rate and blood pressure were measured up to 6 hours after surgery. In addition, patient satisfaction was assessed postoperatively.

RESULTS

Haloperidol and ondansetron have the same effect on postoperative nausea and vomiting in the recovery room and ward. It was found that the trend of Visual Analog Scale variable changes in the recovery room was similar in the haloperidol and ondansetron group ( P = 0.58); it was also true for the ward ( P = 0.79). Comparing the length of stay in a recovery room in the 2 groups was not statistically significant ( P = 0.19). In addition, the 2 groups did not differ in satisfaction postoperatively ( P = 0.82).

CONCLUSION

Haloperidol and ondansetron had an equal effect on reducing nausea and vomiting in the recovery room and ward after laparoscopic cholecystectomy. Patient satisfaction and length of stay in the recovery room did not differ between groups.

Prevalence and time course of postoperative nausea and vomiting and severe pain in patients under general anesthesia with patient-controlled intravenous analgesia

Introduction

Postoperative nausea and vomiting (PONV) and pain are common and distressing complications in patients undergoing surgery. However, it remains uncertain whether timing of the postoperative course or the diel rhythm influences the occurrence of PONV or severe pain. Therefore, we aimed to explore the temporal distribution of PONV and severe pain.

Material and methods

In this prospective observational study, we enrolled patients aged 18-65 years with American Society of Anesthesiologists classifications I-III, who were scheduled for surgery under general anesthesia. Patients were visited postoperatively at regular intervals (every 6 h over a 24-h period). Incidence of PONV was recorded and categorized based on real-time divisions: before dawn (00:00-05:59), morning (06:00-11:59), afternoon (12:00-17:59), and evening (18:00-23:59) and as sequential periods (i.e., 0-6, 6-12, 12-18, and 18-24 h). Severe pain and use of additional remedies were also recorded.

Results

A total of 724 patients were included in the final analysis. Of these, 14.92 % experienced PONV within the first 6 h, and 8.29 % received antiemetic therapy. Occurrence of PONV and administration of remedies declined over the 24-h postoperative period. The lowest rate of PONV was observed during the pre-dawn hours (5.66 %). There was no statistically significant difference in the incidence of PONV 24-h postoperatively between surgeries with different end times. Patients underwent orthopedic surgeries had the highest incidence of PONV during 18:00-23:59, gynecological surgery patients had the highest incidence at 12:00-17:59, and 6:00-11:59 for other surgery patients. All patients had the lowest incidence during 0:00-5:59. During the initial 6-h postoperative period, 24.59 % of patients experienced severe pain, which declined in the remaining episodes. Patients who underwent orthopedic and gynecological surgeries exhibited similar temporal patterns and distribution characteristics of PONV and severe pain.

Discussion

Both PONV and severe pain declined within the 24-h postoperative period, particularly within the first 6 h. Additionally, the onset patterns of PONV vary among patients undergoing different types of surgeries, all patients demonstrated decreased susceptibility to PONV between 00:00-05:59. Our findings enhance prevention and treatment strategies within an optimized timeframe during the postoperative course.

A Postoperative Nausea and Vomiting Update: Current information on New Drugs, Old Drugs, Rescue/Treatment, Combination Therapies and Nontraditional Modalities

This article's objective is to present the latest evidence and information on the management of postoperative nausea and vomiting (PONV). PONV continues to affect 30% of the surgical population causing patient dissatisfaction, extending length of stay, and increasing overall costs. This review includes the introduction of 2 new intravenous formulations of antiemetics (amisulpride, aprepitant), updates on nontraditional therapies, suggestions for combination prophylaxis, emerging data on rescue treatment, and considerations for special populations and settings. Both of the new antiemetics provide promising options for pharmacologic interventions for PONV with favorable safety profiles.

Incidence of Bacteriobilia and the Correlation with Antibioticoprophylaxis in Low-Risk Patients Submitted to Elective Videolaparoscopic Cholecystectomy: A Randomized Clinical Trial

Cholelithiasis has a major impact on global health and affects an average of 20% of the Western population. The main risk factors are females, age over 40 years, obesity and pregnancy. Most of the time it is asymptomatic, but when there are symptoms, they are generally nonspecific. Bile was considered sterile, but today it is known that it contains a complex bacterial flora, which causes biofilm in the gallbladder and gallstones. Among the main bacteria associated with cholelithiasis are Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, species of Enterococcus spp. and Acinetobacter spp. Antibiotic prophylaxis is used in an attempt to reduce postoperative infections, especially at the surgical site. However, some authors found no relationship between the use of antibiotic prophylaxis and a lower risk of surgical site infection. Thus, the aim of this double-blind randomized clinical trial was to compare the existence or not of bacteriobilia in patients at low anesthetic risk who underwent videolaparoscopic cholecystectomy, and its correlation with the use of prophylactic antibiotics. This study included 40 patients between 18 and 65 years old, diagnosed with cholelithiasis, symptomatic or not, with low anesthetic risk classified by the American Society of Anesthesiology in ASA I or ASA II, without complications or previous manipulation of the bile duct, who underwent elective video cholecystectomy, divided into two groups: Experimental Group A (n = 20), which received 2 g of Cephalotin (first-generation Cephalosporin, Keflin®, ABL antibiotics, Cosmópolis, Brazil) during anesthetic induction, and Control Group B (n = 20), where no antibiotics were administered until bile collection. After the procedure, a bile sample was collected and culture and antibiogram were performed. In the sample, 22 (55%) were classified as ASA I and 18 (45%) as ASA II. It was observed that 81.8% of the patients who had a positive culture did not use antibiotics, against 18.2% of those who used prophylaxis. When comparing patients regarding anesthetic risk, ASA I patients had a positive culture in 9.1% of cases, against 90.9% in patients classified as ASA II. It was concluded that patients with higher anesthetic risk (ASA II) have a higher chance of bacteriobilia and benefit from antibiotic prophylaxis when compared to patients with lower anesthetic risk (ASA I).

Comparing the effects of continuous infusion of esmolol and ramosetron alone and in combination on nausea and vomiting after laparoscopic cholecystectomy: A prospective, randomized, double-blind study

BACKGROUND

Postoperative nausea and vomiting (PONV) is a common complication of laparoscopic cholecystectomy. Although PONV is usually mild, severe thing can delay recovery and prolong hospitalization. We aimed to investigate the effects of ramosetron and esmolol, alone and in combination, on PONV, and pain.

METHODS

We enrolled 165 patients in their 20s to 50s who had an American Society of Anesthesiology physical status score of 1 or 2 and were scheduled to undergo laparoscopic cholecystectomy. They were randomly allocated into 3 groups: groups R, E, and E+R. Patients in group R received 0.3 mg of ramosetron following surgery. Those in group E were intravenously administered a bolus of esmolol (1.0 mg/kg) before endotracheal intubation. They were continuously infused with esmolol during the surgery to maintain their heart rate at 60 to 100 beats per minute and mean blood pressure at 60 to 100 mm Hg, followed by a bolus of esmolol (1.0 mg/kg) following surgery. Patients in group E+R were intravenously administered a bolus of esmolol (1.0 mg/kg) before endotracheal intubation, infused esmolol during surgery, and administered 0.3 mg of ramosetron and a bolus of esmolol (1.0 mg/kg) following surgery. We monitored the PONV stages (none, nausea, retching, and vomiting) and symptom severity in 3 postoperative stages (0-30 minutes, 30 minutes to 6 hours, and 6-24 hours), the latter by using the visual analog scale (VAS). We conducted an analysis of variance to compare VAS scores between groups.

RESULTS

Patients in groups E (mean ± standard deviation VAS score, 3.62 ± 1.00) and E+R (3.66 ± 0.71) exhibited less pain (P < .05) until 30 minutes following surgery compared to group R (5.72 ± 1.41). More patients in group E (28/50, 56%) experienced nausea compared to those in groups R (15/50, 30%) and E+R (8/50, 16%) until 30 minutes after surgery (P < .05). However, there were no differences in the severity of retching and vomiting between the groups in any of the phases (P > .05).

CONCLUSION

Despite reducing pain after laparoscopic cholecystectomy, esmolol did not prevent PONV, whether used alone or in combination with ramosetron.

Is Prevention of Postoperative Vomiting Surgery Dependent? A Retrospective Cohort Study of Total Knee Arthroplasty

The study of postoperative nausea and vomiting (PONV) has been ongoing since the early days of general anesthesia. The search for risk factors of PONV and the development of new agents to treat PONV are the two main strategies to combat the adverse side effects of general anesthesia. Female sex, non-smoking status, a history of PONV/motion sickness, and postoperative opioid use are the four independent risk factors for PONV derived after a series of prospective studies, evidence-based systematic reviews, and meta-analyses. The two frequently asked questions that arise ask whether risk factors apply to different clinical settings and whether prevention measures of PONV can be surgery dependent. We conducted a comprehensive review of 665 patients who underwent primary total knee arthroplasty (TKA) between January and December 2019. As nausea is subjective and its measurement is not standardized, postoperative vomiting (POV) was used as a study endpoint. The exclusion criteria were desflurane anesthesia, spinal anesthesia, anesthesia without bispectral index monitoring, and day surgery. Three well-recognized risk factors, consisting of body weight, sevoflurane consumption, and postoperative opioid consumption, were not considered as independent risk factors of POV, while female sex, preoperative adductor canal block (ACB), and dexamethasone were identified as being so in this study. The risk of POV in the female sex was 2.49 times that in the male sex; however, when dexamethasone was used, this risk was reduced by >40% compared with no antiemetic use, and by >50% when patients received preoperative ACB compared with those without the block. The clinical characteristics of our TKA patients—female dominance, old age, and their fairly constant body weights that were distinct from those of other surgical patients—suggested that age may play a crucial role in determining the relative contributions of the different risk factors of POV. We concluded that risk factors of POV are dependent on clinical settings. Based on these results, it is reasonable to speculate that a surgery-dependent plan for the prevention of POV is feasible for patients in similar clinical settings.
