Perioperative Pain Management in Bariatric Anesthesia.

Weight loss (bariatric) surgery is the most commonly performed elective surgical procedure in patients with morbid obesity. In this review, we provide an evidence-based update on perioperative pain management in bariatric anesthesia. We mention some newer preoperative aspects-medical optimization, physical preparation, patient education, and psychosocial factors-that can all improve pain management.

Effect of intraperitoneal local anesthesia on enhanced recovery outcomes after bariatric surgery: a randomized controlled pilot study.

Background: Patients with extreme obesity are at high risk for adverse perioperative events, especially when opioid-centric analgesic protocols are used, and perioperative pain management interventions in bariatric surgery could improve safety, outcomes and satisfaction. We aimed to evaluate the impact of intraperitoneal local anesthesia (IPLA) on enhanced recovery after bariatric surgery (ERABS) outcomes.

Methods: We conducted a prospective double-blind randomized controlled pilot study in adherence to an a priori peer-reviewed protocol.

Intravenous Lidocaine for Acute Pain: A Single-Institution Retrospective Study.

Background: In the perioperative period, intravenous lidocaine has been used as an opioid-sparing systemic analgesic with additional anti-inflammatory and anti-hyperalgesic properties.

Objective: The aim of this retrospective study was to review the utilization, efficacy, and safety of intravenous lidocaine on our Acute Pain Service (APS) and identify surgical and patient populations where this intervention was found to be useful.

Patients And Methods: This retrospective study was designed to assess acute pain management in patients who received an intravenous lidocaine infusion between February 2013 and December 2017.

Randomised, double-blinded, placebo-controlled trial to investigate the role of laparoscopic transversus abdominis plane block in gastric bypass surgery: a study protocol.

Introduction: Evaluating the efficacy of a laparoscopically guided, surgical transversus abdominis plane (TAP) and rectus sheath (RS) block in reducing analgesic consumption while improving functional outcomes in patients undergoing laparoscopic bariatric surgery.

Methods: 150 patients Living with obesity undergoing elective laparoscopic Roux-En-Y gastric bypass for obesity will be recruited to this double-blinded, placebo-controlled randomised controlled trial from a Bariatric Centre of Excellence over a period of 6 months. Patients will be electronically randomised on a 1:1 basis to either an intervention or placebo group.

Perioperative Pain Management in Morbid Obesity.

Morbid obesity (MO) is becoming increasingly prevalent worldwide and is associated with both altered physiology and increased co-morbidities. Together, these can render the perioperative pain management in patients with MO particularly challenging. With the higher incidence of sleep-disordered breathing in this patient population, traditional opioid-centric pain management can often result in opioid-induced ventilatory impairment and increased morbidity and/or mortality.

Perioperative Pain and Addiction Interdisciplinary Network (PAIN) clinical practice advisory for perioperative management of buprenorphine: results of a modified Delphi process.

Until recently, the belief that adequate pain management was not achievable while patients remained on buprenorphine was the impetus for the perioperative discontinuation of buprenorphine. We aimed to use an expert consensus Delphi-based survey technique to 1) specify the need for perioperative guidelines in this context and 2) offer a set of recommendations for the perioperative management of these patients. The major recommendation of this practice advisory is to continue buprenorphine therapy in the perioperative period.

"CAPS" Cardiac Acute Pain Services-A Nationwide Survey From Canada.

Objectives: Acute Pain Services (APS) are well-established worldwide; however, their availability and use in cardiac surgery units are less widespread and, even where present, may be provided less consistently. The authors undertook this survey to assess the current organization of Cardiac Acute Pain Services (CAPS) in Canada.

Design: This was a prospectively administered survey.

Acute pain management in morbid obesity - an evidence based clinical update.

Increasing numbers of patients with morbid obesity are presenting for surgery and their acute pain management requires an evidence-based clinical update. The objective of this study was to complete a literature review for acute pain management in morbid obesity and provide an evidence-based clinical update with recommendations. Using standardized search terms, in March 2015, we completed a literature search to determine evidence for different acute pain pharmacological modalities in morbid obesity.

Perioperative use of pregabalin for acute pain-a systematic review and meta-analysis.

Evidence supporting postoperative pain management using pregabalin as an adjunct intervention across various surgical pain models is lacking. The objective of this systematic review was to evaluate "model-specific" comparative effectiveness and harms of pregabalin following a previously published systematic review protocol. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched from inception through August 2013.

Assessing the feasibility of a randomised, double-blinded, placebo-controlled trial to investigate the role of intraperitoneal ropivacaine in gastric bypass surgery: a protocol.

Introduction: Postoperative pain control remains a major challenge for surgical procedures, including laparoscopic gastric bypass. Pain management is particularly relevant in obese patients who experience a higher number of cardiovascular and pulmonary events. Effective pain management may reduce their risk of serious postoperative complication, such as deep vein thrombosis and pulmonary emboli.

Airway management in cervical spine ankylosing spondylitis: Between a rock and a hard place.

We report the perioperative course of a patient with long standing ankylosing spondylitis with severe dysphagia due to large anterior cervical syndesmophytes at the level of the epiglottis. He was scheduled to undergo anterior cervical decompression and the surgical approach possibly precluded an elective pre-operative tracheostomy. We performed a modified awake fibreoptic nasal intubation through a split nasopharyngeal airway while adequate oxygenation was ensured through a modified nasal trumpet inserted in the other nares.

A protocol for a systematic review for perioperative pregabalin use.

Background: Perioperative pain management has recently been revolutionized with the recognition of novel mechanisms and introduction of newer drugs. Many randomized trials have studied the use of the gabapentinoid anti-epileptic, pregabalin, in acute pain. Published systematic reviews suggest that using pregabalin for perioperative pain management may decrease analgesic requirements and pain scores, at the expense of troublesome side effects.

Cardiac arrest in the operating room requiring prolonged resuscitation.

Purpose: Prolonged cardiopulmonary resuscitation (CPR) is often associated with limited success and poor long-term outcomes. The purpose of this report is to present the case of a patient who suffered an unanticipated cardiac arrest in the operating room and survived following a prolonged period of CPR.

Clinical Features: A previously healthy 53-yr-old male with inflammatory bowel disease was diagnosed with a perforated bowel and underwent emergency exploratory laparotomy under general anesthesia.

Postoperative respiratory depression with pregabalin: a case series and a preoperative decision algorithm.

Pregabalin is gaining popularity in the perioperative period for its usefulness in treating neuropathic pain and its apparent opioid- sparing effect. The present report describes the perioperative course of three patients who received pregabalin and experienced significant respiratory depression in the postoperative period. All three patients consented to the report and publication of the present case series.
