Review Meta Analysis Comparative StudyComparison of invasive and noninvasive blood hemoglobin measurement in the operating room: a systematic review and meta-analysis.
Noninvasive hemoglobin (Hb)-monitoring devices are new inventions in pulse oximeter systems that show hemoglobin levels continuously. The aim of this systematic review and meta-analysis was to evaluate the accuracy and precision of noninvasive versus standard central laboratory Hb measurements in the operating room. We systematically searched multiple databases. ⋯ A total of 28 studies on 2000 participants were included in the meta-analysis. Meta-analysis results of mean differences between noninvasive and the central laboratory Hb measurements in overall pooled random effects were - 0.27 (95% LoA (0.44, - 0.10); P value < 0.05). According to this meta-analysis, noninvasive hemoglobin measurement has acceptable accuracy in comparison with the standard invasive method.

ReviewEmergent endotracheal intubation associated cardiac arrest, risks, and emergency implications.
Emergent endotracheal intubation (ETI)-related cardiac arrest (CA) is a life-threatening complication that is poorly documented. Definitions and risk factors for CA during or directly after emergent ETI have not been clearly established and may represent modifiable means of improving patient outcomes. We conducted a review of the literature to assess the incidence and risk factors associated with ETI-related CA in the Emergency Department (ED) as well as in the inpatient setting outside of the operating room. ⋯ Definitions of ETI-related CA also varied considerably ranging from within 5 min to within 60 min of intubation; however, the majority of ETI-related CA cases occurred within 10 min. Hemodynamic factors such as SI, hypotension, and hypoxemia were associated with increased rates of CA. ETI-related CA may represent a potentially modifiable complication that can improve patient outcomes in critically ill patients presenting in the ED.

ReviewBrain white matter lesions and postoperative cognitive dysfunction: a review.
Postoperative cognitive dysfunction (POCD) is a serious complication of anesthesia and surgery, and the major risk factor of POCD is aging. Although the exact pathophysiology of POCD remains unknown, two possible and reliable mechanisms have been proposed: neuroinflammation and neurodegeneration, i.e., amyloid β accumulation and/or tau protein phosphorylation, by surgery and/or general anesthetics. White matter lesions (WML) are produced by chronic cerebral hypoperfusion, frequently observed in elderly people, and closely related to cognitive decline. As recent studies have revealed that WML are a significant risk factor for POCD in humans, and we previously also demonstrated that persistent hypocapnea or hypotension caused neuronal damage in the caudoputamen or the hippocampus in a rat model of chronic cerebral hypoperfusion, which features global cerebral WML without neuronal damage and is recognized as a good model of human vascular dementia especially in elderly people, we hypothesize that in addition to those two previously proposed mechanisms, perioperative vital sign changes that cause reductions in cerebral blood flow might contribute to POCD in patients with WML, whose cerebral blood flow is already considerably decreased.

Meta Analysis Comparative StudyComparative effectiveness of interventions for managing postoperative catheter-related bladder discomfort: a systematic review and network meta-analysis.
Although many drugs or interventions have been studied to manage catheter-related bladder discomfort (CRBD), their comparative effectiveness is unknown. We attempted to assess the comparative effectiveness of the strategies to manage CRBD in patients undergoing urologic surgery including amikacin, solifenacin, darifenacin, butylscopolamine, dexmedetomidine, gabapentin, glycopyrrolate, ketamine, oxybutynin, resiniferatoxin, tolterodine, tramadol, caudal block, dorsal penile nerve block, lidocaine-prilocaine cream. ⋯ Gabapentin was ranked best regarding the overall incidence of CRBD, while tolterodine was ranked best in reducing the severity of CRBD. However, a firm conclusion cannot be made from our analysis due to small-study number and heterogeneity regarding study setting and outcome measurement.

ReviewAmyotrophic lateral sclerosis and anesthesia: a case series and review of the literature.
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to death due to respiratory failure. This report describes the perioperative characteristics of ALS patients who underwent procedures with anesthesia at our institution. ⋯ When caring for patients with ALS, the perioperative team must be prepared to treat potentially complex medical conditions that may not be directly related to the procedure and anesthetic management. However, minor procedures performed with minimal sedation may be safely performed on an ambulatory basis.
