Randomized clinical trial comparing two different techniques of local anesthesia (subcutaneous versus subcutaneous & deep infiltration) for postoperative pain in patients undergoing open appendecectomy.

This study compared the postoperative analgesic effect of local anesthetic (LA) injected subcutaneous (SC) alone versus local anesthetic injected both SC and deep in patients undergoing open appendecectomy operations. Sixty patients ASA class I-II undergoing open appendecectomy for presumed acute appendicitis will be randomly assigned into three groups. After routine monitoring, anesthesia induction was performed with propofol, fentanyl and, cis-atracurium; later, maintenance was continued with isoflurane.

Fluid optimization with hydroxyethyl starch 130/0.4 compared with modified fluid gelatin guided by esophageal Doppler during major abdominal surgeries.

Perioperative fluid therapy has a direct bearing on patient outcome and accordingly should be tailored individually. Thus the efficacy of HES 130/0.4 was compared to modified fluid gelatin for volume expansion during major abdominal surgery guided by transesophageal Doppler (TED).

Subpleural versus deep lung biopsies obtained during pleuroscopy for histological examination: an experimental animal study.

Background: Lung biopsies obtained during medical pleuroscopy using coagulating forceps could represent a cost-effective alternative to surgical lung biopsies in patients with diffuse parenchymal lung diseases (DPLD). However, it is not clear whether these patients should undergo deeplung biopsies rather than more superficial subpleural lung biopsies.

Objectives: The aim of this experimental animal study was to compare gross and microscopic features of deep and subpleural pleuroscopic lung biopsy samples.

Controlled mechanical ventilation with LMA Sureme versus i-gel in anesthetized adult patients.

The efficacy, safety and ease of insertion of LMA Supreme and the i-gel in adult cases undergoing elective surgical procedures requiring general anesthesia with controlled mechanical ventilation. This study included 60 ASA physical status I-II adult patients of both sexes scheduled for elective surgical procedures under general anesthesia. Patients were randomly allocated into one of two groups; LMA-S GI (n=30) and i-gel GII (n=30).

Effect of general and epidural anesthesia on hemostasis and fibrinolysis in hepatic patients.

This study was designed to compare the effect of general anesthesia using isoflurane and epidural anesthesia using ropivacaine on hemostasis in hepatic patients. Sixty patients were randomly allocated into two groups to receive either general or epidural anesthesia which further subdivided into control and hepatic subgroups. Blood samples were collected preoperatively, immediate post-operatively and on third post-operative day to measure hemoglobin (Hb), platelet count (PLT),), prothrombin time (PT), partial thromboplastin time (PTT), and thrombin time (TT).

Efficacy of epidural dexamethasone versus fentanyl on postoperative analgesia.

Purpose: Dexamethasone has analgesic, anti-inflammatory, and antiemetic effects. This prospective, randomized, double-blind, controlled study was designed to evaluate the efficacy of adding dexamethasone versus fentanyl to epidural bupivacaine on postoperative analgesia.

Methods: Ninety patients ASA I-II scheduled for lower abdominal surgeries were randomly allocated into three groups to receive a total of 10 mL epidural plain bupivacaine 0.
