Abstract
BACKGROUND Ketamine has been considered as an adjunct for children who do not reach their predefined target sedation depth. However, there is limited evidence regarding the use of ketamine as a prolonged infusion (i.e., >24 hours) in the pediatric intensive care unit (PICU). OBJECTIVE We sought to evaluate the safety and effectiveness of continuous ketamine infusion for >24 hours in mechanically ventilated children. METHODS We conducted a prospective cohort study in a tertiary PICU from January 2020 to December 2022. The primary outcome was the incidence of adverse events (AEs) after ketamine initiation. The secondary outcome included assessing the median proportion of time the patient spent on the Richmond Agitation-Sedation Scale (RASS) goal after ketamine infusion. Patients were also divided into two groups based on the sedative regimen, ketamine-based or non-ketamine-based, to assess the incidence of delirium. RESULTS A total of 269 patients were enrolled: 73 in the ketamine group and 196 in the non-ketamine group. The median infusion rate of ketamine was 1.4 mg/kg/h. Delirium occurred in 16 (22%) patients with ketamine and 15 (7.6%) patients without ketamine (p = 0.006). After adjusting for covariates, logistic regression showed that delirium was associated with comorbidities (odds ratio [OR] 4.2), neurodevelopmental delay (OR 0.23), fentanyl use (OR 7.35), and ketamine use (OR 4.17). Thirty-one (42%) of the patients experienced at least one AE following ketamine infusion. Other AEs likely related to ketamine were hypertension (n = 4), hypersecretion (n = 14), tachycardia (n = 6), and nystagmus (n = 2). There were no significant changes in hemodynamic variables 24 h after the initiation of ketamine. Regarding the secondary outcomes, patients were at their goal RASS level for a median of 76% (range 68-80.5%) of the time in the 24 hours before ketamine initiation, compared with 84% (range 74.5-90%) of the time during the 24 h after ketamine initiation (p < 0.001). The infusion rate of ketamine did not significantly affect concomitant analgesic and sedative infusions. The ketamine group experienced a longer duration of mechanical ventilation and a longer length of stay in the PICU and hospital than the non-ketamine group. CONCLUSION The use of ketamine infusion in PICU patients may be associated with an increased rate of adverse events, especially delirium. High-quality studies are needed before ketamine can be broadly recommended or adopted earlier in the sedation protocol.

Abstract
OBJECTIVE To analyze the COVID-19 pandemic in Brazil, a continental-sized country, considered as an emerging economy but with several regional nuances, focusing on the availability of human resources, especially for intensive care units. METHODS The database of the National Registry of Health Facilities was accessed. Healthcare professionals in the care of COVID-19 were georeferenced. We correlated the number of professionals with the parameters used by the World Health Organization. According to the Brazilian Intensive Care Medicine Association, we correlated the data for adult intensive care unit beds in each state with the number of professionals for each ten intensive care unit beds. The number of professionals, beds, and cases were then organized by state. RESULTS The number of physicians per 100 thousand inhabitants followed the World Health Organization recommendations; however, the number of nurses did not. The number of intensivists, registered nurses, nurse technicians specialized in intensive care, and respiratory therapists, necessary for every ten intensive care beds, was not enough for any of these professional categories. A complete team of critical care specialists was available for 10% of intensive care unit beds in Brazil. CONCLUSION There is a shortage of professionals for intensive care unit, as we demonstrated for Brazil. Intensive care physical resources to be efficiently used require extremely specialized human resources; therefore, planning human resources is just as crucial as planning physical and structural resources.

Does admission time matter in a paediatric intensive care unit? A prospective cohort study. J Paediatr Child Health 2021; 57:1296-1302. [PMID: 33788334 DOI: 10.1111/jpc.15471] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Revised: 01/27/2021] [Accepted: 03/21/2021] [Indexed: 11/29/2022]
Abstract
AIM Studies assessing the association between admission time to paediatric intensive care unit (PICU) and mortality are sparse with conflicting results. We aimed to evaluate the impact of time of admission on PICU mortality within 48 h after admission. METHODS This was a single-centre prospective cohort. We collected data from all consecutive children aged 1 month to 16 years over 10 years. RESULTS We included a total of 1368 admissions, with a PICU mortality of 6.6%. Compared with daytime admissions, the overall mortality rate (5.3% vs. 8.5%, P = 0.026) and the mortality within 48 h after admission were higher for those admitted during night-time (2% vs. 4.2%, P = 0.021). There were no differences between mortality rates and the day of admission (weekend admissions vs. weekday admissions). The adjusted odds of death within 48 h after admission was 2.5 (95% confidence interval = 1.22-5.24, P = 0.012) for patients admitted at night-time. A secondary analysis assessing trends in mortality rates during admission showed that the last 5 years of study were more responsible for the chances of death within 48 h (odds ratio = 7.6, 95% confidence interval = 1.91-30.17, P = 0.0039). CONCLUSION Admission to the PICU during night shifts was strongly associated with death compared to daytime admissions. A time analysis of the moment of admission is necessary as a metric of quality of care to identify the interruption or improvement in the continuity of care. Further studies are needed to assess the modified contributing factors.

Abstract
It is unknown if the requirement for high dose of vasopressor (HDV) represents a poor outcome in pediatric septic shock. This is a retrospective observational analysis with data obtained from a single center. We evaluated the association between the use of HDV and survival in these patients. A total of 62 children (38 survivors and 24 nonsurvivors) were assessed. The dose of vasopressor (hazard ratio 2.06) and oliguria (hazard ratio 3.17) was independently associated with mortality. The peak of vasopressor was the best prognostic predictor. A cutoff of 1.3 μg/kg/min was associated with mortality with a sensitivity of 75% and specificity of 89%. Vasopressor administration higher than 1.3 μg/kg/min was associated with increased mortality in children with septic shock.

Abstract
OBJECTIVE While studies have focused on early readmissions or readmissions during the same hospitalization in a pediatric intensive care unit, little is known about the children with recurrent admissions. We sought to assess the characteristics of patients readmitted within 1 year in a Brazilian pediatric intensive care unit. METHODS This was a retrospective study carried out in a tertiary pediatric intensive care unit. The outcome was the maximum number of readmissions experienced by each child within any 365-day interval during a 5-year follow-up period. RESULTS Of the 758 total eligible admissions, 75 patients (9.8%) were readmissions. Those patients accounted for 33% of all pediatric intensive care unit bed care days. Median time to readmission was 73 days for all readmissions. Logistic regression showed that complex chronic conditions (odds ratio 1.07), severe to moderate cognitive disability (odds ratio 1.08), and use of technology assistance (odds ratio 1.17) were associated with readmissions. Multiple admissions had a significantly prolonged duration of mechanical ventilation (8 vs. 6 days), longer length of pediatric intensive care unit (7 vs 4 days) and hospital stays (20 vs 9 days), and higher mortality rate (21.3% vs 5.1%) compared with index admissions. CONCLUSION The rate of pediatric intensive care unit readmissions within 1 year was low; however, it was associated with a relevant number of bed care days and worse outcomes. A 30-day index of readmission may be inadequate to mirror the burden of pediatric intensive care unit readmissions. Patients with complex chronic conditions, poor functional status or technology assistance are at higher risk for readmissions. Future studies should address the impact of qualitative interventions on healthcare and recurrent admissions.

Abstract
Purpose:Although several studies assess unplanned extubation (UE) in children, few have addressed determinants of UE and factors associated with reintubation in a case-controlled manner. We aimed to identify the risk factors and outcomes associated with UE in a pediatric intensive care unit.Methods:Cases of UE were randomly matched with control patients at a ratio of 1:4 for age, severity of illness, and admission diagnosis. For cases and controls, we also collected data associated with UE events, reintubation, and outcomes.Results:We analyzed 94 UE patients (0.75 UE per 100 intubation days) and found no differences in demographics between the 2 groups. Logistic regression revealed that patient agitation (odds ratio [OR]: 2.44; 95% confidence interval [CI]: 1.28-4.65), continuous sedation infusion (OR: 3.27; 95% CI: 1.70-6.29), night shifts (OR: 9.16; 95% CI: 4.25-19.72), in-charge nurse experience <2 years (OR: 2.38; 95% CI: 1.13-4.99), and oxygenation index (OI) >5 (OR: 76.9; 95% CI: 16.79-352.47) were associated with UE. Risk factors for reintubation after UE included prior level of sedation (COMFORT score < 27; OR: 7.93; 95% CI: 2.30-27.29), copious secretion (OR: 11.88; 95% CI: 2.20-64.05), and OI > 5 (OR: 9.32; 95% CI: 2.45-35.48).Conclusions:This case–control study showed that both patient- and nurse-associated risk factors were related to UE. Risk factors associated with reintubation included lower levels of consciousness, copious secretions, and higher OI. Further evidence-based studies, including a larger sample size, are warranted to identify predisposing factors in UEs.

Abstract
PURPOSE Reintubation following unplanned extubation (UE) is often required and associated with increased morbidity; however, knowledge of risk factors leading to reintubation and subsequent outcomes in children is still lacking. We sought to determine the incidence, risk factors, and outcomes related to reintubation after UEs. METHODS All mechanically ventilated children were prospectively tracked for UEs over a 7-year period in a pediatric intensive care unit. For each UE event, data associated with reintubation within 24 hours and outcomes were collected. RESULTS Of 757 intubated patients, 87 UE occurred out of 11 335 intubation days (0.76 UE/100 intubation days), with 57 (65%) requiring reintubation. Most of the UEs that did not require reintubation were already weaning ventilator settings prior to UE (73%). Univariate analysis showed that younger children (<1 year) required reintubation more frequently after an UE. Patients experiencing UE during weaning experienced significantly fewer reintubations, whereas 90% of patients with full mechanical ventilation support required reintubation. Logistic regression revealed that requirement of full ventilator support (odds ratio: 37.5) and a COMFORT score <26 (odds ratio: 5.5) were associated with UE failure. There were no differences between reintubated and nonreintubated patients regarding the length of hospital stay, ventilator-associated pneumonia rate, need for tracheostomy, and mortality. Cardiovascular and respiratory complications were seen in 33% of the reintubations. CONCLUSION The rate of reintubation is high in children experiencing UE. Requirement of full ventilator support and a COMFORT score <26 are associated with reintubation. Prospective research is required to better understand the reintubation decisions and needs.

Abstract
BACKGROUND AND OBJECTIVE Benzodiazepines and opioids are commonly used in pediatric intensive care unit. However, there is no previous study assessing the use of administering these drugs combined (single solution) or separately. We sought to evaluate the impact of these 2 different methods of providing sedation/analgesia in pediatric intensive care unit. METHODS One hundred twelve patients mechanically ventilated for more than 48 hours were randomized to receive a protocolized sedation regime comprising midazolam and fentanyl either separately (group 1, 57 patients) or combined as a single solution (group 2, 55 patients). Primary end point variable was the cumulated dose of midazolam and fentanyl. RESULTS The median cumulated doses of both fentanyl (0.19 vs 0.37 mg/kg, P < .05) and midazolam (28.8 vs 45.6 mg/kg, P < .05) required in group 2 were higher when compared with those of group 1. Moreover, group 2 patients had a significantly longer time of vasopressor drugs requirement and a higher number of patients developing tolerance. CONCLUSION Patients who received a single solution of midazolam and fentanyl had a higher cumulated dose of compared with those patients who did not. The potential risk for long-term neurologic effects on developing brains associated with this finding should be considered.

Abstract
AIM Although the modified Clinical Pulmonary Infection Score (CPIS) has been used to guide treatment decisions in adults with ventilator-associated pneumonia (VAP), paediatric studies are lacking. We assessed a modified CPIS tool to define VAP resolution and identify treatment failure at an early stage. METHODS We identified 70 mechanically ventilated children with VAP according to the Center for Disease Control criteria. Modified CPIS was initially measured at VAP onset and then three and five days afterwards. Children were defined as low risk or high risk based on a cut-off score of six. RESULTS There were 50 high-risk and 20 low-risk patients. Culture results were positive in 64% of the high-risk patients and just 10% of the low-risk patients. Patients on adequate therapy significantly improved their CPIS scores by day three, regardless of the likelihood of VAP. A lack of score improvement demonstrated sensitivity of 100% and specificity of 83% when it came to detecting treatment failure. The area under the receiver operating curve was 0.92. CONCLUSION Serial modified CPIS measurements showed that low-risk patients with negative cultures at day three should be considered for a short course of antibiotics. In contrast, high-risk patients with no score improvement were potentially failing their treatment.

Abstract
BACKGROUND The absence of pediatric surgeons in many centers results in restriction of patient access to pediatric subspecialty care. The aim of this study was to compare the outcomes of children treated for appendicitis by pediatric surgeons (PS) and by general surgeons (GS). METHODS This was a retrospective review of the charts of all consecutive patients <16 years old who underwent appendectomy during 2 years The primary outcome measure was the overall rate of complications. Secondary outcome measures included length of hospital stay (LOS), symptom duration, time from emergency department diagnosis to surgery, and readmission rate within 30 days. RESULTS A total of 94 patients (PS group, n = 66; GS group, n = 28) were included. PS patients were younger. For patients with complicated appendicitis, complications were significantly more prevalent in the GS group (57% vs 15%; P = 0.0001). Median LOS was not significantly different between the two groups for complicated appendicitis, but patients with non-complicated appendicitis had a significant longer LOS when treated by PS (3.74 ± 1.5 vs 2.57 ± 1.21 days; P = 0.0041). Patients in the PS group had a prolonged use of antibiotics (2 vs 4 days; P = 0.001), and longer LOS (3 vs 4 days; P = 0.0018). CONCLUSIONS Overall complication rates were similar between PS and GS. Complications were significantly more prevalent in patients with complicated appendicitis who were treated by GS.

Abstract
RATIONALE Although the modified clinical pulmonary infection score (mCPIS) has been endorsed by national organizations, only a very few pediatric studies have assessed it for the diagnosis of ventilator-associated pneumonia (VAP). METHODS Seventy children were prospectively included if they fulfilled the diagnosis criteria for VAP referenced by the Centers for Disease Control and Prevention. The primary outcome was performance of mCPIS calculated on day 1 to accurately identify VAP as defined by microbiological data. RESULTS The data showed that an mCPIS of 6 or higher had a sensitivity of 94%, specificity of 50%, positive predictive value of 64%, negative predictive value of 90%, a positive likelihood ratio of 1.88, and a negative likelihood ratio of 0.11. The area under the receiver operating characteristic curve was 0.70. A positive posttest result increased the disease probability by 15.4%, whereas a negative test result reduced the probability by 38.6%. Patients with an mCPIS of 6 or higher had longer length of mechanical ventilation and pediatric intensive care unit stay compared with patients with an mCPIS lower than 6. CONCLUSION The mCPIS had a clinically acceptable performance, and it can be a helpful screening tool for VAP diagnosis. An mCPIS lower than 6 was highly able in distinguishing patients without VAP. Despite its high sensitivity and negative predictive value of this score, further studies are required to assess the use of mCPIS in guiding therapeutic decisions.

Abstract
OBJECTIVE To update the state of knowledge on unplanned extubations (UEs) in neonatal ICUs. This review focuses on the following topics: incidence, risk factors, reintubation after UE, outcomes, and prevention. METHODS The MEDLINE, EMBASE, CINAHL, Scielo, Lilacs, and Cochrane databases were searched for relevant publications from January 1, 1950, through January 30, 2012. Fifteen articles were selected for data abstraction. The search strategy included the following key words: "unplanned extubation," "accidental extubation," "self extubation," "unintentional extubation," "unexpected extubation," "inadvertent extubation," "unintended extubation," "spontaneous extubation," "treatment interference," and "airway accident." Study quality was assessed using the Newcastle-Ottawa scale. Grades of recommendation were assessed according to the Oxford Centre for Evidence-Based Medicine's levels of evidence system. Studies with Newcastle-Ottawa scale score ≥ 5 that included appropriate statistical analysis were deemed of high methodological quality. RESULTS The overall mean Newcastle-Ottawa scale score was 3.5. UE rates ranged from 0.14 to 5.3 UEs/100 intubation days, or 1% to 80.8%. Risk factors included restlessness/agitation (13-89%), poor fixation of endotracheal tube (8.5-31%), tube manipulation at the time of UE (17-30%), and performance of a patient procedure at bedside (27.5-51%). One study showed that every day on mechanical ventilation increased the UE risk 3% (relative risk 1.03, P < .001). The association between birth weight/gestational age and UE is controversial. Reintubation rates ranged from 8.3% to 100%. There is still a gap of information about strategies addressed to reduce the incidence of UE. The best method of endotracheal tube securement remains a controversial issue. CONCLUSIONS Despite numerous publications on UE, there are few studies assessing preventive strategies for adverse events and there is a lack of randomized clinical trials. Recommendations are proposed based on the current available literature.

Abstract
OBJECTIVE To evaluate the performance of the Transport Risk Index of Physiologic Stability (TRIPS) score at admission for early mortality prediction. METHODS The study included all consecutive outborn infants admitted to a single neonatal intensive care unit (NICU) over a 3-year period. The data collected included demographic variables, 7-day NICU mortality, and severe (≥ grade 3) intraventricular hemorrhage (IVH), TRIPS score at admission, and Score for Neonatal Acute Physiology II (SNAP-II) and SNAP-Perinatal Extension-II (SNAPPE-II) scores. RESULTS A total of 175 neonates were enrolled. TRIPS at admission discriminated 7-day mortality from survival with a receiver operating characteristic (ROC) area of 0.80, and predictive performance of TRIPS for severe IVH showed a ROC area of 0.67. The TRIPS had good calibration for all strata (p = 0.49). For gestational age (GA) >32 weeks, the area under the curve (AUC) for TRIPS was 0.71, whereas the AUC for GA ≤32 weeks was 0.99 for 7-day mortality. Predictive performance of TRIPS for 7-day mortality was similar to that of SNAP-II and SNAPPE-II. CONCLUSION TRIPS score at admission had a good performance to discriminate high-risk patients for 7-day mortality, mainly infants with GA ≤32 weeks. TRIPS might be a useful triage tool if applied at the time of first contact with a transport service.

Abstract
Aminophylline exerts a renovascular effect, acting by adenosine receptor blockade or type IV phosphodiesterase inhibition. Clinically, these drugs have been used with furosemide to induce diuresis in adults and neonates. However, reports on use of aminophylline in diuretic-dependent children are limited to a few studies. We report a case series of four critically ill children unresponsive to furosemide continuous infusion who were subsequently given aminophylline as an adjunct diuretic in the treatment of fluid overload. No side effects were evident. Administration of aminophylline at low doses (3 mg/kg) successfully promoted increased urine output over the 6-h study period in all four children.

Abstract
BACKGROUND The aim of this study was to evaluate the effectiveness and safety of intravenous ketamine-propofol admixture ("ketofol") in the same syringe for procedural sedation and analgesia in children undergoing bone marrow aspiration. METHODS This was a prospective, observational pilot study. Patients aged between 4 and 12 years requiring sedation for bone marrow aspiration were included. Ketofol (1:1 mixture of ketamine 10 mg/mL and propofol 10 mg/mL) was given intravenously in 0.5 mg/kg aliquots each with a 1-min interval and titrated to reach sedation levels of 3 or 4 (Ramsay score). The primary outcome was patient satisfaction with the degree of sedation. Secondary outcomes included injection pain, total sedation time, recovery time, hemodynamic and respiratory parameters, and adverse events. RESULTS A total of 20 patients were enrolled in the study. The median total dose of ketofol administered was 1.25 mg/kg each of propofol and ketamine (95%CI 0.77-2 mg/kg). The median score on the visual analog scale was 0 (extremely comfortable) (0-1.5; 95%CI 0.2-2.2). Median recovery time was 23 min (20.5-28 min; 95%CI 17.1-51.2). The incidence of injection pain was 2/20. Two patients had transient diplopia and one child reported dreams. No patients had hypotension, vomiting or required airway intervention. CONCLUSION Ketofol provided effective sedation, which was reflected in the high degree of satisfaction recorded by children requiring procedural sedation and analgesia for bone marrow aspiration. We also observed rapid recovery and no clinically significant complications. A large number of patients is required to evaluate and validate these findings.

Abstract
BACKGROUND Early peritoneal recurrence of gastric carcinoma following curative resection remains a great challenge in the treatment and prevention of this disease. AIM To analyze the relationship between levels of tumor markers, carcinoembryonic antigen (CEA) and CA 19-9 in the sera and peritoneal washing, and anatomopathological aspects of the gastric carcinoma. METHODS Of the 46 patients in the study, 29 (63.0%) were males and 17 (37.0%) females. Mean age was 63.6 +/- 11.7 years (31 to 91 years). Peripheral venous blood samples were collected from the upper limb vein from both patient groups after anesthetic induction, in order to determine serum levels of CEA and CA 19-9. After the end of the procedure, 50 mL of physiologic solution was introduced into the bottom of the Douglas sack and a portion aspirated to determine CEA and CA 19-9 levels in the peritoneal washing. Levels of CEA and CA 19-9 in the sera and peritoneal washing were compared to the following variables: lesion diameter < or = 4 cm or > 4 cm, lymph node involvement, angiolymphatic invasion, depth of invasion into gastric wall, and initial or late stage. RESULTS Sera CEA levels were significantly higher in patients with lesions >5 cm. CEA levels in the sera and peritoneal washing were significantly greater in patients with signet ring cell gastric carcinoma. In addition, levels of CEA in peripheral blood and peritoneal washing showed significant association with the degree of carcinoma penetration into the gastric wall, while sera CEA was significantly higher in patients at more advanced stages. There was no significant difference between sera and peritoneal CEA values regarding grade of differentiation. Patients with gastric lesions measuring > 5 cm and more differentiated lesions had significantly higher sera CA 19-9 values. In patients with lymph nodes invasion by gastric carcinoma, CA 19-9 levels in peritoneal washing were significantly higher than in peripheral blood. Levels of CA 19-9 in peritoneal washing were significantly greater at advanced stages than the initial stage of the gastric carcinoma. CONCLUSIONS Elevated levels of CA 19-9 in peritoneal washing were significantly associated with more advance stages of gastric carcinoma and was more reliable predictive factor for staging than sera CA 19-9 levels. CEA levels in the sera more accurately reflected neoplasia stage than levels in peritoneal washing.

Severe acute renal failure in a child: a rare complication of anicteric leptospirosis. Pediatr Nephrol 2007; 22:1971-4.

Abstract
A 14-year-old male patient was admitted with fever, vomiting, muscular pain, mainly in the lower limbs, oliguria and oedema. The presence of rats in the vicinity of the home was reported. Laboratory tests on admission revealed severely compromised renal function and increased phosphokinase creatine and thrombocytopenia. Although the patient presented an atypical course without jaundice or meningeal involvement, early dialytic treatment was administered concomitant with empiric antibiotic therapy for leptospirosis. The probable infected serogroup by serology was Autumnalis. This atypical case illustrates that, in the presence of fever, renal failure, rhabdomyolysis and thrombocytopenia, leptospirosis should be considered, even in the absence of jaundice or meningitis, especially if there is a history of contact with carrier animals.

Abstract
UNLABELLED Enterococci are an uncommon cause of CNS infection. A 20 month-old boy, diagnosed with hydrocephalus with ventriculoperitoneal shunt and history of lengthy hospitalization and use of wide spectrum antibiotics, was admitted to the pediatric intensive care unit diagnosed with ventriculitis. On the 14th day of empirical antibiotic therapy (vancomycin and meropenem) the child presented fever while the CSF sample culture evidenced vancomycin-resistant Enterococcus faecium. The patient received intravenous linezolid achieving cerebrospinal fluid sterilization. CONCLUSION Intravenous linezolid appears to be a safe and effective therapy for vancomycin-resistant enterococcus ventriculoperitoneal shunt infection.

Abstract
BACKGROUND There is a lack of studies evaluating procedural sedation for insertion of central venous catheters (CVC) in pediatric patients in emergency departments or pediatric intensive care units (PICU). This study was designed to evaluate whether there is a difference in the total sedation time for CVC insertion in nonintubated children receiving two sedation regimens. METHODS Patients were prospectively randomized to receive either midazolam/fentanyl (M/F) or midazolam/ketamine (M/K) i.v. The Children's Hospital of Wiscosin Sedation Scale was used to score the sedation level. RESULTS Fifty seven patients were studied (28 M/F and 29 M/K). Group M/F received midazolam (0.24 +/- 0.11 mg.kg(-1)) and fentanyl (1.68 +/- 0.83 microg.kg(-1)) and group M/K received midazolam (0.26 +/- 0.09 mg.kg(-1)) and ketamine (1.40 +/- 0.72 mg.kg(-1)). The groups were similar in age, weight, risk classification time and sedation level. Median total sedation times for M/F and M/K were 97 vs 105 min, respectively (P = 0.67). Minor complications occurred in 3.5% (M/F) vs 20.7% (M/K) (P = 0.03). M/F promoted a greater reduction in respiratory rate (P = 0.005). CONCLUSIONS In this study of nonventilated children in PICU undergoing central line placement, M/F and M/K provided a clinically comparable total sedation time. However, the M/K sedation regimen was associated with a higher rate of minor complications. A longer period of study is required to assess the efficacy and safety of these sedative agents for PICU procedures in nonintubated children.

Abstract
Hypokalemia can result in life-threatening complications if not treated appropriately. Although hypokalemia is a frequent adverse effect of amphotericin B therapy, there are no reports in the pediatric literature on hypokalemia-associated rhabdomyolysis induced by this drug. A ten-year-old boy with a history of one week amphotericin B treatment was admitted with weakness of the lower extremities, inability to walk and calf pain. Laboratory tests showed a serum potassium of 1.7 mEq/L and a serum creatinine phosphokinase of 3937 U/L plus myoglobulinuria. Following fluid expansion and intravenous potassium replacement, the patient progressed to achieve full regression of muscular weakness after one week. This report highlights hypokalemia as a rare cause of rhabdomyolysis. Patients on amphotericin B should be checked for this rare yet potentially life-threatening complication.

Abstract
UNLABELLED Negative-pressure pulmonary edema is a rare but life-threatening complication of upper airway obstruction. Because negative-pressure pulmonary edema may occur in a large spectrum of pathologies associated with upper airway obstruction, awareness of this condition is crucial during daily clinical practice. We report a case of negative-pressure pulmonary edema during anesthetic recovery to highlight this condition. CASE A 2-year-old boy was scheduled for orchidopexy under general anesthesia. Shortly after an uneventful operation, the patient presented airway obstruction. Serious oxygen desaturation and bradycardia ensued, during inefficient attempts at positive-pressure ventilation. After emergency intubation, copious pink secretions emerged from the airway. Pulmonary edema was confirmed by clinical examination, pulse oximetry, and chest radiography. The finding of pulmonary edema was resolved within 24 hours after mechanical ventilation and positive end-expiratory pressure. The child suffered no sequelae. This report highlights the clinical features of negative-pressure pulmonary edema and serves as a reminder to the pediatrician who must be able to recognize and initiate treatment for conditions that are uncommon but life-threatening.
