Randomized Controlled Trial Multicenter StudyEffect of Midazolam in Addition to Propofol and Opiate Sedation on the Quality of Recovery After Colonoscopy: A Randomized Clinical Trial.
There is a concern that midazolam, when used as a component of sedation for colonoscopy, may impair cognition and prolong recovery. We aimed to identify whether midazolam produced short- and longer-term effects on multiple dimensions of recovery including cognition. ⋯ The addition of midazolam 0.04 mg·kg as adjunct to propofol and opiate sedation for elective colonoscopy did not show evidence of any significant differences in recovery in the cognitive domain of the PostopQRS, overall quality of recovery as measured by the PostopQRS, or emergence and hospital discharge times. The use of midazolam should be determined by the anesthesiologist.

Randomized Controlled Trial Comparative StudyA Prospective, Randomized Trial Comparing Respiratory Status During Anesthesia for Airway Stenting: Spontaneous Respiration Versus Controlled Ventilation With Muscle Relaxants.
Airway stenting is a procedure in which a stent is inserted into a stenotic site of the airway. The safest method of ventilation for airway stenting is controversial. A prospective randomized interventional study was conducted on airway stenting. We conducted this study to investigate whether controlled ventilation with muscle relaxants (MR) during airway stenting reduces the incidence of desaturation events (percutaneous oxygen saturation [SpO2] <95%) in comparison with spontaneous respiration (SP). ⋯ Controlled ventilation with MR during airway stenting reduced the incidence of desaturation events, maintaining a favorable respiratory status.

Meta AnalysisElectroencephalography-Guided Anesthetic Delivery for Preventing Postoperative Delirium in Adults: An Updated Meta-analysis.
Postoperative delirium is a major debilitating complication for patients and is associated with poor outcomes. Previous studies have suggested that excessive general anesthesia may lead to postoperative delirium. Electroencephalography (EEG)-based monitors have been administered in clinical practice in an attempt to deliver appropriate anesthesia. The aim of this updated meta-analysis was to evaluate the current body of research concerning the effects of EEG-based monitor on postoperative delirium. ⋯ The current evidence is not sufficient to support the prevention effects of EEG monitor on postoperative delirium. More robustly designed and well-conducted studies with emphasis on this matter are warranted.

ReviewAirway management in the operating room and interventional suites in known or suspected COVID-19 adult patients: a practical review.
Current evidence suggests that coronavirus disease 2019 (COVID-19) spread occurs via respiratory droplets (particles >5 µm) and possibly through aerosol. The rate of transmission remains high during airway management. This was evident during the 2003 severe acute respiratory syndrome epidemic where those who were involved in tracheal intubation had a higher risk of infection than those who were not involved (odds ratio 6.6). ⋯ Awake intubation should be avoided unless it is absolutely necessary. Extubation is a high-risk procedure for aerosol and droplet spread and needs thorough planning and preparation. As updates and modifications in the management of COVID-19 are still evolving, local guidelines, appraised at regular intervals, are vital in optimizing clinical management.

Comparative Study Observational StudyNeuraxial Labor Analgesia Utilization, Incidence of Postdural Puncture Headache, and Epidural Blood Patch Placement for Privately Insured Parturients in the United States (2008-2015).
Neuraxial analgesia is the gold standard for labor analgesia in the United States, and postdural puncture headache (PDPH) is one of the most common complications. PDPH is frequently treated with an epidural blood patch (EBP), but conservative treatment approaches remain common. Our current understanding of the incidence of PDPH and the frequency of EBP utilization is heavily based on reports from academic medical centers. We studied a private insurance database to provide estimates of neuraxial labor analgesia (NLA) use and PDPH and EBP incidence in the United States. ⋯ This analysis confirms findings of prior studies regarding the present utilization of neuraxial analgesia and the incidence of PDPH. When compared to patients undergoing VD with NLA, patients having CD without NLA had a higher incidence of PDPH, presumably due to intentional dural puncture. Women having CD with a prior NLA had a lower incidence of PDPH, possibly due to avoidance of pushing during the second stage of labor. EBP was a commonly pursued strategy for the treatment of PDPH and was more commonly pursued in patients with a history of NLA. Repeat EBP was rare.
