Comparative Evaluation of Direct Laryngoscopy Versus GlideScope for the Purpose of Laryngoscopy Management and Intubation in Candidates of Cesarean Delivery with General Anesthesia.

Background: The present study aimed at comparing the hemodynamic responses to laryngoscopy and initiation of intubation with either direct or video-assisted laryngoscopy.

Materials And Methods: This double-blind clinical trial was performed on 90 pregnant women candidates for cesarean section under general anesthesia. The participants were divided into two groups.

Efficacy of plasmapheresis in neutropenic patients suffering from cytokine storm because of severe COVID-19 infection.

Background: With the emergence of the coronavirus disease 2019 (COVID-19) and inability of healthcare systems to control the disease, various therapeutic theories with controversial responses have been proposed. Plasmapheresis was administered as a medication. However, the knowledge of its efficacy and indications is inadequate.

Comparison Prophylactic Effects of Gargling Different Doses of Ketamine on Attenuating Postoperative Sore Throat: A Single-Blind Randomized Controlled Trial.

Context: Postoperative sore throat (POST) is a common annoying problem following endotracheal (ET) intubation.

Aims: Comparing the impact of low and high doses of ketamine gargle on lowering POST incidence and severity.

Settings And Design: 96 patients selected for septoplasty surgery under general anesthesia were investigated through a single-blind randomized controlled trial.

Comparing the prophylactic effects of oral gabapentin, pregabalin, and celecoxib on postoperative pain management in orthopedic surgery of the lower extremity: A double-blind randomized controlled trial.

Background: Lower extremity pain after orthopedic surgery is so frequent that has led to many treatment modalities. This study aims to compare the prophylactic effects of oral gabapentin, pregabalin, and celecoxib on reducing postsurgical pain of the lower extremity orthopedic surgery.

Materials And Methods: In a double-blind randomized controlled trial, 120 patients were randomly divided into four groups using block design randomization.

A randomized controlled trial for the effectiveness of intraarticular versus intravenous midazolam on pain after knee arthroscopy.

Background: This double-blinded, randomized clinical trial was designed to evaluate the comparison of intravenous versus intraarticular (IA) administration of midazolam on postoperative pain after knee arthroscopy.

Materials And Methods: In this study, 75 patients randomized in three groups to receive 75 mc/kg IA injection of midazolam and 10 ml intravenous injection of isotonic saline (Group I), 75 mc/kg intravenous injection of midazolam and 10 cc IA injection of isotonic saline (Group II) or IA and intravenous injection of isotonic saline (Group III) at the end of knee arthroscopy. Pain scores, time until the first request for analgesics, cumulative analgesic consumption, satisfaction, sedation, and complications as studied outcomes were assessed.

Spinal anesthesia versus general anesthesia for elective lumbar spine surgery: A randomized clinical trial.

Background: Either general or regional anesthesia can be used for lumbar disk surgery. The common anesthetic technique is general anesthesia (GA). The aim of this study was to compare the intra and postoperative outcomes of spinal anesthesia (SA) with GA in these patients.

Pre-incisional infiltration of tonsils with dexamethasone dose not reduce posttonsillectomy vomiting and pain in children.

Background And Objective: Recently, dexamethasone has been found to have a prophylactic effect on postoperative vomiting and pain in children undergoing tonsillectomy. However, few studies have examined the preemptive analgesic effects of dexamethasone after tonsillectomy. The aim of this study was to evaluate the effect of pre-incisional infiltration of tonsils with dexamethasone on the incidence and severity of postoperative pain and vomiting in children undergoing tonsillectomy under general anesthesia.

Low dose intravenous midazolam for prevention of PONV, in lower abdominal surgery--preoperative vs intraoperative administration.

Background: The aim of the present study was to compare anti-emetic efficacy of low dose midazolam premedication (35 microg/kg) 15 minutes before induction of anesthesia with midazolam (35 microg/kg) administered intravenously 30 min before conclusion of surgery, in patients undergoing lower abdominal surgery under general anesthesia.

Methods: Sixty patients were assigned to one of three equal groups: Group MP (n = 20), which received intravenous midazolam 35 microg/kg in a volume of 3 ml 15 minutes before induction of anesthesia and 3 ml normal saline 30 minutes before extubation. Group MI (n = 20), which received 3 ml normal saline 15 minutes before induction of anesthesia and intravenous midazolam 35 microg/kg in a volume of 3 ml 30 minutes before extubation.

The preventative analgesic effect of preincisional peritonsillar infiltration of two low doses of ketamine for postoperative pain relief in children following adenotonsillectomy. A randomized, double-blind, placebo-controlled study.

Background: In literature, the use of ketamine for the preventative analgesia in the management of postoperative pain is controversial. The purpose of the present study was the clinical assessment of the efficacy of preincisional peritonsillar infiltration of two doses of ketamine on postoperative pain relief compared with peritonsillar saline in children undergoing adenotonsillectomy.

Methods/materials: Seventy-five ASA physical status I and II patients, aged 3-12 years, scheduled for adenotonsillectomy were enrolled in this randomized, double-blind, placebo-controlled study.

M/F ratios of four different closing loops: 3D analysis using the finite element method (FEM).

Background: It has been claimed that the opus loop is capable of delivering a constant and optimum M/F ratio without the need for gable bends.

Objective: To compare the forces, moments and moment/force (M/F) ratios of the opus loop, L-loop, T-loop and vertical helical closing loop (VHC loop) in a segmented arch with the finite element method (FEM).

Methods: The FEM was used to compare 3D models of closing loops in rectangular (0.
