Intraoperative alpha-band power in frontal electrodes may provide helpful information about the balance of hypnosis and analgesia and has been associated with reduced occurrence of delirium in the postanesthesia care unit. Recent studies suggest that narrow-band power computations from neural power spectra can benefit from separating periodic and aperiodic components of the electroencephalogram. This study investigates whether such techniques are more useful in separating patients with and without delirium in the postanesthesia care unit at the group level as opposed to conventional power spectra. ⋯ Increased alpha-band power during emergence in patients who did not develop perioperative neurocognitive disorders can be traced back to an increase in oscillatory alpha activity and an overall increase in aperiodic broadband power. Although the differences between patients with and without perioperative neurocognitive disorders can be detected relying on traditional methods, the separation of the signal allows a more detailed analysis. This may enable clinicians to detect patients at risk for developing perioperative neurocognitive disorders in the postanesthesia care unit early in the emergence phase.

Randomized Controlled TrialEffect of preoperative warming on intraoperative hypothermia and postoperative functional recovery in total hip arthroplasty: a randomized clinical trial.
Intraoperative hypothermia is associated with increased morbidity and impaired postoperative recovery. Direct anterior-approached total hip arthroplasty (ATHA) may lead to significant thermal loss. We aimed to assess whether preoperative warming had an impact on intraoperative hypothermia and postoperative functional recovery after ATHA. ⋯ In ATHA, pre-warming delays and reduces intraoperative heat loss, impacting patient comfort and postoperative functional recovery.

Patient Satisfaction With, and Outcomes of, Ultrasound-Guided Regional Anesthesia at a Referral Hospital in Tanzania: A Cross-Sectional Study.
Regional anesthesia techniques are increasingly used in high-income countries (HICs) for both surgical anesthesia and postoperative analgesia. However, regional anesthesia has not been utilized to the same degree in low- to middle-income countries (LMICs) due to a lack of resources and trained personnel. This study evaluates patient satisfaction with, and outcomes of, ultrasound-guided regional anesthesia for extremity surgery at Kilimanjaro Christian Medical Center (KCMC) in the Northeastern zone of Tanzania. ⋯ Our study found that ultrasound-guided regional anesthesia in a resource-constrained setting was effective for extremity surgery and resulted in high patient satisfaction. No complications occurred. The use of ultrasound-guided regional anesthesia shows promise for the safe and effective care of patients undergoing extremity surgery in LMICs.
