A Lumbar Paravertebral Space Ultrasound Lumbar Plexus Block Technique for Hip Fracture Surgery in the Elderly.

Ultrasound imaging of peripheral nerves is challenging in elderly population. In cases involving the lumbar plexus (LP), we have employed ultrasound imaging and neurostimulation guidance for successful localization and block of the LP. The postero-medial segment of the psoas muscle (PSM), superior to the vertebral body and anterior to the transverse process ("corner pocket") was used as an imaging landmark for the implementation of the LP block.

Pre-Procedural Lumbar Neuraxial Ultrasound-A Systematic Review of Randomized Controlled Trials and Meta-Analysis.

A pre-procedural ultrasound of the lumbar spine is frequently used to facilitate neuraxial procedures. The aim of this review is to examine the evidence sustaining the utilization of pre-procedural neuraxial ultrasound compared to conventional methods. We perform a systematic review of randomized controlled trials with meta-analyses.

The effect of 0.5 L 6% hydroxyethyl starch 130/0.42 versus 1 L Ringer's lactate preload on the hemodynamic status of parturients undergoing spinal anesthesia for elective cesarean delivery using arterial pulse contour analysis.

Purpose: Fluid loading attenuates the hypotensive response to spinal anesthesia (SA). This study aimed to compare the preload efficacy of 0.5 L hydroxyethyl starch (HES) versus 1 L Ringer's lactate (R/L) in the prevention of hypotension after SA for elective cesarean delivery (CD).

Mannitol and renal dysfunction after endovascular aortic aneurysm repair procedures: a randomized trial.

Objective: Endovascular aortic aneurysm repair (EVAR) may result in deterioration of renal function. Mannitol has renovascular and antioxidant properties that could prove beneficial in this respect.

Design: A randomized prospective study.

Analgesia with remifentanil versus anesthesia with propofol-alfentanil for transvaginal oocyte retrieval: a randomized trial on their impact on in vitro fertilization outcome.

Background: The aim of this study was to compare the effects of analgesia with remifentanil versus anesthesia with propofol and alfentanil on in vitro fertilization outcome.

Methods: The study included 58 women undergoing ultrasound transvaginal oocyte retrieval, who were randomized to receive either analgesia with remifentanil (n = 29) or anesthesia with propofol and alfentanil (n = 29). The subjects were compared for number of collected and matured oocytes, fertilization rate, cleavage rate, implantation rate, pregnancy rate, and embryo quality.

Greek surgical patients' satisfaction related to perioperative anesthetic services in an academic institute.

Background: Patient satisfaction is an increasingly appreciated measure of outcome for health care procedures. The purpose of this study was to evaluate Greek surgical patients' satisfaction with perioperative anesthetic services and to determine which factors maximize satisfaction level through all phases of perioperative care.

Methods: Adult Greek patients admitted for elective surgery in an academic hospital were included in the study.

The differential impact of volatile and intravenous anaesthetics on stress response in the swine.

Objective: To compare the effects of various anaesthetics on stress response in the presence and absence of surgical stimulation.

Design: Twenty-nine pigs scheduled to undergo surgical central vein catheter placement were randomly allocated to receive only sedation with ketamine-midazolam (group SHAM, n=5) or general anaesthesia with either propofol 8 mg/kg/h (group PROP, n=8), sevoflurane 1.0 MAC (group SEVO, n=8) or desflurane 1.
