Randomized Controlled Trial Comparative StudyComparison of efficacy of transversus abdominis plane block and iliohypogastric/ilioinguinal nerve block for postoperative pain management in patients undergoing inguinal herniorrhaphy with spinal anesthesia: a prospective randomized controlled open-label study.
The purpose of this study was to compare the effects of lateral abdominal transversus abdominis plane block (TAP block) and iliohypogastric/ilioinguinal nerve block (IHINB) under ultrasound guidance for postoperative pain management of inguinal hernia repair. Secondary purposes were to compare the complication rates of the two techniques and to examine the effects of TAP block and IHINB on chronic postoperative pain. ⋯ We conclude that administration of TAP block or IHINB for patients undergoing inguinal herniorrhaphy reduces the intensity of both acute and chronic postoperative pain and additional analgesic requirements.

Randomized Controlled Trial Comparative StudyPreventive effect of a vapocoolant spray on propofol-induced pain: a prospective, double-blind, randomized study.
Propofol causes injection pain. Although lidocaine pre-treatment via venous occlusion is known to be the most effective way, it still has some inconvenience. We implemented this study to compare the effect of a vapocoolant spray with lidocaine pre-treatment. ⋯ Vapocoolant spray showed a similar effect to lidocaine in analgesia and lowered the incidence of a metallic taste. These resulted in greater satisfaction with the vapocoolant spray compared with lidocaine. Vapocoolant spray is an effective and convenient way to prevent propofol-induced pain.

Randomized Controlled TrialThe response to Trendelenburg position is minimally affected by underlying hemodynamic conditions in patients with aortic stenosis.
Trendelenburg positioning is commonly used to temporarily treat intraoperative hypotension. The Trendelenburg position improves cardiac output in normovolemic or anesthetized patients, but not hypovolemic or non-anesthetized patients. Therefore, the response to Trendelenburg positioning may vary depending on patient population or hemodynamic conditions. We thus tested the hypothesis that the effectiveness of the Trendelenburg position, as indicated by an increase in cardiac output, improves after replacement of a stenotic aortic valve. Secondarily, we evaluated whether measurements of left ventricular preload, systolic function, or afterload were associated with the response to Trendelenburg positioning. ⋯ The response to Trendelenburg positioning improved following AVR, but by a clinically unimportant amount. The response to Trendelenburg positioning was independent of hemodynamic conditions.

Randomized Controlled TrialProtective multimodal analgesia with etoricoxib and spinal anesthesia in inguinal hernia repair: a randomized controlled trial.
Inguinal hernia repair is a common procedure, and can be performed under spinal anesthesia. Although adequate analgesia is crucial to postoperative recovery, the optimal protective analgesic regimen remains to be established. ⋯ The addition of etoricoxib to spinal anesthesia as a multimodal protective regimen can improve pain control after inguinal hernia repair. The optimal dose and applicability to other operations remains to be established.

Randomized Controlled Trial Comparative StudyElectroencephalographic effect of age-adjusted 1 MAC desflurane and sevoflurane in young, middle-aged, and elderly patients.
We examined the hypothesis that 1 minimum alveolar concentration (MAC) of desflurane and sevoflurane provides different depth of anesthesia. ⋯ BIS as well as SEF95 were lower in patients receiving 1 MAC desflurane than those receiving 1 MAC sevoflurane, suggesting that desflurane provides higher depth of anesthesia than sevoflurane at 1 MAC.
