Electric Nerve Stimulation Does Not Correctly Predict Needle-Nerve Distance and Potential Local Anesthetic Spread for Interscalene Brachial Plexus Blockade.

This study evaluated electric nerve stimulation as a nerve location tool. After eliciting motor response in 43 patients undergoing shoulder surgery, the needle tip's position, distance from the closest nerve, and spread of saline were evaluated using ultrasound imaging. The needle's tip resided 1 to 4 mm from the closest nerve in 21, in direct contact with it in 7, and 6 to 18 mm away in 15 patients.

Impact of spinal versus general anesthesia on postoperative pain and long term recurrence after surgery for pilonidal disease.

Study Objective: To assess the effect of the kind of anesthesia on postoperative pain and long term recurrence rate in pilonidal sinus disease.

Design: Retrospective study.

Setting: Surgical departments of German Armed Forces Hospitals in Hamburg, Bad Zwischenahn and Hamm.

The influence of lifestyle (smoking and body mass index) on wound healing and long-term recurrence rate in 534 primary pilonidal sinus patients.

Purpose: With pilonidal sinus disease (PSD) incidence increasing, lifestyle issues have been suspected to be responsible to worsen the results of PSD surgery at the same time. The influence of smoking and body mass index (BMI) on long-term recurrence rate in primary PSD surgery has not been investigated yet.

Methods: A total of 534 patients (German military cohort) were analyzed, comparing the wound healing rates of non-smoker with smoker, as well as recurrence rates in either groups.
