In the peri-operative period, dexamethasone is widely and effectively used for prophylaxis of postoperative nausea and vomiting. The objective of this meta-analysis was to assess the adverse effects of an incidental steroid load of dexamethasone in adult surgical patients. We searched in MEDLINE, Embase, the Cochrane Central Register of Controlled Trials and the Web of Science for randomised controlled trials comparing an incidental steroid load of dexamethasone with a control intervention in adult patients undergoing surgery...

BACKGROUND: To provide a platform for the dissemination of basic knowledge of pain management, a WhatsApp group was created by residents and consultants. Common clinical scenarios, resident queries, and important instructions to be followed by residents with respect to running the Acute Pain Service were discussed in the group. This study evaluates the benefits of this interaction. METHODS: This study was approved by the hospital ethics board and was registered with the Clinical Trial Registry of India...

Drug addiction is present in a significant proportion of the population in the USA and worldwide. Drug addiction can occur with the abuse of many types of substances including cocaine, marijuana, stimulants, alcohol, opioids, and tranquilizers. There is a high likelihood that clinicians will encounter patients with substance abuse disorders on a regular basis with the prevalence of the use of illicit substances and the high rate of abuse of prescription drugs. The use of abuse deterrent formulations of prescription opioid agents, pill counts, and urine drug abuse screenings are all useful strategies...

Treatment options for hyperkalemia have not changed much since the introduction of the cation exchange resin, sodium polystyrene sulfonate (Kayexalate, Covis Pharmaceuticals, Cary, NC), over 50 years ago. Although clinicians of that era did not have ready access to hemodialysis or loop diuretics, the other tools that we use today-calcium, insulin, and bicarbonate-were well known to them. Currently recommended insulin regimens provide too little insulin to achieve blood levels with a maximal kalemic effect and too little glucose to avoid hypoglycemia...

Blood transfusion is one of the most common procedures in patients in hospital so it is imperative that clinicians are knowledgeable about appropriate blood product administration, as well as the signs, symptoms, and management of transfusion reactions. In this Review, we, an international panel, provide a synopsis of the pathophysiology, treatment, and management of each diagnostic category of transfusion reaction using evidence-based recommendations whenever available.

BACKGROUND: Addicted patients have innate tolerance to local anesthetics in both neuraxial and peripheral blocks. Dexmedetomidine (Dex) is a highly selective α2 adrenergic receptor agonist used as additive to increase quality and duration of peripheral nerve blocks. OBJECTIVES: The current study aimed to compare the effect of dexmedetomidine and fentanyl additives on bupivacaine to prolong the duration of block and minimizing side effects. PATIENTS AND METHODS: Patients were candidates for elective surgery less than three hours of lower abdomen or lower extremities surgeries...

BACKGROUND: There are no evidence-based guidelines to dictate when Gallbladder Polyps (GBPs) of varying sizes should be resected. AIM: To identify factors that accurately predict malignant disease in GBP; to provide an evidence-based algorithm for management. METHODS: A systematic review following PRISMA guidelines was performed using terms "gallbladder polyps" AND "polypoid lesion of gallbladder", from January 1993 and September 2013. Inclusion criteria required histopathological report or follow-up of 2 years...

BACKGROUND: Residency training requires work in clinical settings for extended periods of time, resulting in altered sleep patterns, sleep deprivation, and potentially deleterious effects on safe performance of daily activities, including driving a motor vehicle. METHODS: Twenty-nine anesthesiology resident physicians in postgraduate year 2 to 4 drove for 55 min in the Virginia Driving Safety Laboratory using the Driver Guidance System (MBFARR, LLC, USA). Two driving simulator sessions were conducted, one experimental session immediately after the final shift of six consecutive night shifts and one control session at the beginning of a normal day shift (not after call)...

Invasive mechanical ventilation is required when children undergo general anesthesia for any procedure. It is remarkable that one of the most practiced interventions such as pediatric mechanical ventilation is hardly supported by any scientific evidence but rather based on personal experience and data from adults, especially as ventilation itself is increasingly recognized as a harmful intervention that causes ventilator-induced lung injury. The use of low tidal volume and higher levels of positive end-expiratory pressure became an integral part of lung-protective ventilation following the outcomes of clinical trials in critically ill adults...

BACKGROUND: Perineural and IV dexmedetomidine have each been suggested to prolong the duration of analgesia when administered in conjunction with peripheral nerve blocks. In the first randomized, triple-masked, placebo-controlled trial to date, the authors aimed to define and compare the efficacy of perineural and IV dexmedetomidine in prolonging the analgesic duration of single-injection interscalene brachial plexus block (ISB) for outpatient shoulder surgery. METHODS: Ninety-nine patients were randomized to receive ISB using 15 ml ropivacaine, 0...

BACKGROUND: Neuraxial blockade reduces the dose requirements of sedative agents. It is unclear whether neuraxial blockade affects the pharmacokinetics and/or the pharmacodynamics of IV hypnotics. We therefore studied the influence of epidural blockade on the pharmacokinetics of propofol in patients scheduled for general surgery. METHODS: Twenty-eight patients were randomly divided into 4 groups, in a double-blind manner, to receive 0, 50, 100, or 150 mg epidural ropivacaine...

BACKGROUND: Hip fracture surgery on elderly patients is associated with a high incidence of morbidity and mortality. The aim of this study is to identify the risk factors related to the postoperative mortality and complications following hip fracture surgery on elderly patients. METHODS: In this retrospective study, the medical records of elderly patients (aged 65 years or older) who underwent hip fracture surgery from January 2011 to June 2014 were reviewed. A total of 464 patients were involved...

These guidelines provide a strategy to manage unanticipated difficulty with tracheal intubation. They are founded on published evidence. Where evidence is lacking, they have been directed by feedback from members of the Difficult Airway Society and based on expert opinion. These guidelines have been informed by advances in the understanding of crisis management; they emphasize the recognition and declaration of difficulty during airway management. A simplified, single algorithm now covers unanticipated difficulties in both routine intubation and rapid sequence induction...

BACKGROUND: Incorrect endobronchial placement of the tracheal tube can lead to serious complications. Hence, it is necessary to determine the accuracy of tracheal tube positioning. Markers are included on tracheal tubes, in the process of their manufacture, as indicators of approximate intubation depth. In addition, continuous chest auscultation has been used for determining the proper position of the tube. We examined insertion depth using the cuff depth and continuous chest auscultation method (CC method), compared with insertion depth determined by the marker method, to assess the accuracy of these methods...

PURPOSE OF REVIEW: Obesity along with its pathophysiological changes increases risk of intraoperative and perioperative respiratory complications. The aim of this review is to highlight recent updates in preoxygenation techniques and intraoperative ventilation strategies in obese patients to optimize gas exchange and pulmonary mechanics and reduce pulmonary complications. RECENT FINDINGS: There is no gold standard in preoxygenation or intraoperative ventilatory management protocol for obese patients...

BACKGROUND: It is well recognized that increased transfusion volumes are associated with increased morbidity and mortality, but dose-response relations between high- and very-high-dose transfusion and clinical outcomes have not been described previously. In this study, the authors assessed (1) the dose-response relation over a wide range of transfusion volumes for morbidity and mortality and (2) other clinical predictors of adverse outcomes. METHODS: The authors retrospectively analyzed electronic medical records for 272,592 medical and surgical patients (excluding those with hematologic malignancies), 3,523 of whom received transfusion (10 or greater erythrocyte units throughout the hospital stay), to create dose-response curves for transfusion volumes and in-hospital morbidity and mortality...
