Multicenter Study Comparative Study Clinical Trial
Fast-track anesthesia in patients undergoing outpatient laparoscopic cholecystectomy: comparison of sevoflurane with total intravenous anesthesia.
The use of short-acting anesthetics has introduced a "fast-track anesthesia" concept in outpatient surgery which provides discharge of the patients from operation room directly to the phase II recovery area without entering into postanesthesia care unit. The aim of this prospective and randomized study was to compare general anesthesia using sevoflurane with propofol-remifentanil-based total intravenous anesthesia (TIVA) for fast-track eligibility in patients undergoing outpatient laparoscopic cholecystectomy. The secondary aim was to compare 2 discharge scoring systems: White's Fast-Tracking Scoring System (WFTSS) and Modified Aldrete Scoring Systems (MASS) with regard to postanesthesia care unit bypass rate and postoperative problems. ⋯ The ratio of fast-track eligible patients was higher and times to fast-track eligibility were shorter in group TIVA compared with group sevoflurane (82.1% vs 57.5% and 8 minutes vs 12 minutes; P<.05). The primary factors that have inhibited fast-tracking were desaturation, hemodynamic instability, pain, and postoperative nausea and vomiting, respectively. Postoperative nausea and vomiting presented a major difference in the rate of fast-track ineligibility between groups (4 patients in group sevoflurane, whereas none in group TIVA; P<.05). The fast-track ratio was lower with the WFTSS compared with MASS in group sevoflurane (57.5% vs 77.5%, P<.05), but similar in group TIVA.

Multicenter Study
Consequences of not relieving negative internal pressure of a medication vial: A survey and simulation study.
The glass vial of acetaminophen as an intravenous preparation (Acelio®, Terumo, Japan) has a strong internal negative pressure. The aim of our study was to determine if this negative pressure could result in medication administration errors if not released prior to connecting to the IV set. ⋯ A considerable number of anesthesiologists experienced consequences caused by the negative pressure inside the Acelio® vial. This can also cause aspiration of the contents of the syringe pump.

Randomized Controlled Trial
Ultrasound-guided transversus abdominis plane block for postoperative analgesia in living liver donors: A prospective, randomized, double-blinded clinical trial.
Transversus abdominis plane (TAP) block is a peripheral nerve block that reduces postoperative pain, nausea, vomiting and the need for postoperative opioids following various types of abdominal surgery. The primary aim of the present study was to evaluate the effects of TAP block on postoperative analgesia and opioid consumption in living liver donors in whom a right "J" abdominal incision was used. ⋯ The TAP block reduced 24-h postoperative morphine consumption and contributed to analgesia in living liver donors who underwent upper abdominal wall incisions.

Randomized Controlled Trial Comparative Study
Sevoflurane preserves regional cerebral oxygen saturation better than propofol: Randomized controlled trial.
To investigate possible effects of volatile induction and maintenance anesthesia with sevoflurane (VIMA) and total intravenous anesthesia with propofol (TIVA) on regional cerebral oxygen saturation (rcSo2) during laparoscopic cholecystectomy. ⋯ VIMA technique provides significantly (4%-11%) higher rcSO2 values during general anesthesia for laparoscopic cholecystectomy, when compared with TIVA and also provides significantly less number of critical rcSO2 decreases.

This study aimed to review research on the effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on β-endorphin. NSAIDs are commonly used as anti-inflammatory and analgesic drugs. They are well known for inducing peripheral analgesia by inhibiting cyclooxygenase (COX). ⋯ However, the specific signal transduction pathways between prostaglandin E2 or NSAIDs and β-endorphin are still not quite clear. Whether NSAIDs can lead to the increased content of β-endorphin in all patients after any operation needs further investigation. Further studies should determine the optimal dose when NSAIDs and opioid drugs are used together, and also explore the existence of one NSAID that has the potential to replace the traditional opioid drugs and can achieve adequate analgesia.
