Implementation of Brief Submaximal Cardiopulmonary Testing in a High-Volume Pre-surgical Evaluation Clinic: A feasibility study.

Background: Precise functional capacity assessment is a critical component for preoperative risk stratification. Brief submaximal cardiopulmonary exercise testing (smCPET) has shown diagnostic utility in various cardiopulmonary conditions. Objective: The objective of this study was to determine if smCPET could be implemented in a high-volume pre-surgical evaluation clinic, and, when compared to structured functional capacity surveys, if smCPET could better discriminate low functional capacity (<4.

Perioperative Pulmonary Complications in the Older Adults: The Forgotten System.

With a rapidly aging population and increasing global surgical volumes, managing the elevated risk of perioperative pulmonary complications has become an expanding focus for quality improvement in health care. In this narrative review, we will analyze the evidence-based literature to provide high-quality and actionable management strategies to better detect, stratify risk, optimize, and manage perioperative pulmonary complications in geriatric populations.

Does a single oral administration of amiloride affect spontaneous arterial baroreflex sensitivity and blood pressure variability in healthy young adults?

Preclinical models indicate that amiloride (AMD) reduces baroreflex sensitivity and perturbs homeostatic blood pressure (BP) regulation. However, it remains unclear whether these findings translate to humans. This study investigated whether oral administration of AMD reduces spontaneous cardiac and sympathetic baroreflex sensitivity and perturbs BP regulation in healthy young humans.

Pulmonary Hypertension and the Risk of 30-Day Postoperative Pulmonary Complications after Gastrointestinal Surgical or Endoscopic Procedures: A Retrospective Propensity Score-Weighted Cohort Analysis.

: Pulmonary hypertension (PH) patients are at higher risk of postoperative complications. We analyzed the association of PH with 30-day postoperative pulmonary complications (PPCs). : A single-center propensity score overlap weighting (OW) retrospective cohort study was conducted on 164 patients with a mean pulmonary artery pressure (mPAP) of >20 mmHg within 24 months of undergoing elective inpatient abdominal surgery or endoscopic procedures under general anesthesia and a control cohort (N = 1981).

Estimates of 30-day postoperative pulmonary complications after gastrointestinal endoscopic procedures: A retrospective cohort analysis of a health system population.

The incidence of 30-day postoperative pulmonary complications (PPC) of gastrointestinal endoscopic procedures (GIEP) are not well characterized in the literature. The primary aim of this study was to identify the incidence of 30-day PPC after GIEP within a large healthcare system. We conducted a retrospective cohort study of 5377 patients presenting for GIEP between January 2013 and January 2022.

Perioperative Complications in Patients with Systemic Sclerosis: A Comparative Cohort Analysis.

Background: Systemic sclerosis (SSc) is a rare autoimmune disorder with pathological manifestations affecting multiple organ systems. Few studies have examined perioperative outcomes in patients with this disorder. The primary aim of this retrospective single-center comparative cohort analysis was to estimate the incidence of select perioperative complications in a population of SSc patients.

Identifying, Understanding, and Minimizing Unconscious Cognitive Biases in Perioperative Crisis Management: A Narrative Review.

Rapid clinical decision-making behavior is often based on pattern recognition and other mental shortcuts. Although such behavior is often faster than deliberative thinking, it can also lead to errors due to unconscious cognitive biases (UCBs). UCBs may contribute to inaccurate diagnoses, hamper interpersonal communication, trigger inappropriate clinical interventions, or result in management delays.

Predictors of Failure to Rescue After Postoperative Respiratory Failure: A Retrospective Cohort Analysis of 13,047 Patients Using the ACS-NSQIP Dataset.

Introduction: Death after suffering a postoperative complication (failure to rescue) is an area of concern, and its occurrence after postoperative respiratory failure (PRF) is not well defined. We seek to identify the predictors of failure to rescue in patients who develop PRF.

Methods: A retrospective cohort study of adults undergoing noncardiac surgery who developed PRF (postoperative unplanned intubation and receipt of mechanical ventilation for longer than 48 h) was conducted using the American College of Surgeons National Surgical Quality Improvement Project database.

Emergency use of sugammadex after failure of standard reversal drugs and postoperative pulmonary complications: A retrospective cohort study.

Background And Aims: The use of sugammadex instead of neostigmine for the reversal of neuromuscular blockade may decrease postoperative pulmonary complications. It is unclear if this finding is applicable to situations where sugammadex is administered after the administration of neostigmine. The objective of this study was to compare the incidence of a composite outcome measure of major postoperative pulmonary complications in patients who received sugammadex as a rescue agent after neostigmine versus those who received sugammadex alone for reversal of neuromuscular blockade.

Perioperative Pulmonary Complications in the Elderly: The Forgotten System.

With a rapidly aging population and increasing global surgical volumes, managing the elevated risk of perioperative pulmonary complications has become an expanding focus for quality improvement in health care. In this narrative review, we will analyze the evidence-based literature to provide high-quality and actionable management strategies to better detect, stratify risk, optimize, and manage perioperative pulmonary complications in geriatric populations.

Information Technology-Enhanced Telehealth Consultations Reduce Preoperative Evaluation Center Visits in a Bariatric Surgery Population.

: Preoperative patient evaluation and optimization in a preoperative evaluation center (PEC) has been shown to improve operating room (OR) efficiency and patient care. However, performing preoperative evaluation on all patients scheduled for surgery or procedure would be time- and resource-consuming. Therefore, appropriate patient selection for evaluation at PECs is one aspect of improving PEC efficiency.

A 10-mg dose of amiloride increases time to failure during blood-flow-restricted plantar flexion in healthy adults without influencing blood pressure.

Amiloride has been shown to inhibit acid-sensing ion channels (ASICs), which contribute to ischemia-related muscle pain during exercise. The purpose of this study was to determine if a single oral dose of amiloride would improve exercise tolerance and attenuate blood pressure during blood-flow-restricted (BFR) exercise in healthy adults. Ten subjects (4 females) performed isometric plantar flexion exercise with BFR (30% maximal voluntary contraction) after ingesting either a 10-mg dose of amiloride or a volume-matched placebo (random order).

Perioperative Management of Patients with Idiopathic Pulmonary Fibrosis Undergoing Noncardiac Surgery: A Narrative Review.

Purpose: The idiopathic interstitial pneumonias (IIP) constitute a large cohort of the over 200 subtypes of interstitial lung disease (ILD). Idiopathic pulmonary fibrosis (IPF) is the most widely studied, arguably the most severe etiology of ILD and the most common IIP diagnosis. The objective of this narrative review is to outline the current evidence on optimal perioperative management of IPF.

Persistent Postoperative Vasoplegia After Ureteronephrectomy Due To Suspected Intravesical Gemcitabine Toxicity.

We describe a case of unusually persistent vasoplegia in the postoperative course of a patient recovering after elective right robotic nephroureterectomy with intravesical salvage gemcitabine. In the treatment of patients with intravesical adjuvant therapy, gemcitabine may precipitate persistent vasoplegia requiring further fluid resuscitative efforts, vasopressor support, and other supportive management. This potential adverse event should be considered when all common causes of persistent vasoplegia are ruled out, such as shock related to bleeding, infection, allergic reaction, or pulmonary embolic phenomenon.

Endocrine emergencies in anesthesia.

Purpose Of Review: An increasing number of patients with endocrine disorders will present to the operating rooms. In this review, we outline the common endocrine disorders that the anesthesiologist may face in the perioperative time span, review the controversies in optimal management, as well as summarize the recent literature for the management of these complex patients.

Recent Findings: Perioperative management of pheochromocytoma and paraganglioma has been facilitated by improved medical management and the adoption of minimally invasive surgical techniques.

Perioperative risk factors in patients with idiopathic pulmonary fibrosis: a historical cohort study.

Purpose: Perioperative complications of patients with idiopathic pulmonary fibrosis (IPF) are not well described. The aim of this study was to identify risk factors associated with adverse postoperative outcomes in IPF patients.

Methods: We performed a single-centre historical cohort study of adult patients with IPF who underwent surgery between 2008 and 2018.

An Update on Systemic Sclerosis and its Perioperative Management.

Purpose Of Review: Systemic sclerosis or scleroderma (SSc) is a systemic, immune-mediated disease characterized by abnormal cutaneous and organ-based fibrosis that results in progressive end-organ dysfunction and decreased survival. SSc results in significant challenges for the practicing anesthesiologist due to its rarity, multi-system involvement, and limited evidence-based guidance for optimal perioperative care. In this update, we briefly discuss the recent evidence on the pathophysiology and current management of SSc, review the anesthesia-related literature, and extrapolate these observations into an optimal perioperative strategy for the care of SSc patients.

In a Model of Neuroinflammation Designed to Mimic Delirium, Quetiapine Reduces Cortisol Secretion and Preserves Reversal Learning in the Attentional Set Shifting Task.

Quetiapine, an atypical antipsychotic medication has lacked pre-clinical validation for its purported benefits in the treatment of delirium. This laboratory investigation examined the effects of quetiapine on the attentional set shifting task (ASST), a measure of cognitive flexibility and executive functioning, in a rodent model of lipopolysaccharide (LPS) mediated neuroinflammation. 19 Sprague Dawley female rats were randomly selected to receive intraperitoneal placebo (N = 5), LPS and placebo (N = 7) or LPS and quetiapine (n = 7) and performed the ASST.

Pain management in trauma patients affected by the opioid epidemic: A narrative review.

Acute and chronic pain in trauma patients remains a challenging entity, particularly in the setting of the escalating opioid epidemic. It has been reported that chronic opioid use increases the likelihood of hospital admissions as a result of traumatic injuries. Furthermore, patients admitted with traumatic injuries have a greater than average risk of developing opioid use disorder after discharge.
