Randomized Controlled Trial
The effect of supplemental 70% oxygen on postoperative nausea and vomiting in patients undergoing inguinal hernia surgery.
Postoperative nausea and vomiting (PONV) are among the leading side-effects after surgery performed under general anaesthesia. The role of oxygen as an important method for treatment of PONV was studied. The aim of this study was to compare intraoperative 30% oxygen with 70% oxygen for improvement of PONV in patients undergoing inguinal hernia surgery. ⋯ Supplemental oxygen effectively prevents postoperative nausea and vomiting after inguinal hernia surgery: the higher the arterial oxygen saturation, the less frequent PONV.

Several tools for pain measurement including a Visual Analogue Scale (VAS) and a Verbal Rating Scale (VRS) are currently used in patients with chronic pain. The aim of the present study was to determine which of these two pain tests performs optimally in patients following groin hernia repair. ⋯ Because of lower scale failure rates and overlapping VAS scores per VRS category, the VRS should be favored over the VAS in future postherniorrhaphy pain assessment. If VAS is preferred, the presented cut-off points should be utilized.

The incidence of chronic pain after Kugel herniorrhaphy is not well documented, since it was not used as a primary outcome measure in studies reporting on the Kugel technique. The aim of the present study was to report on the incidence and severity of chronic pain 1 year after Kugel herniorrhaphy and to identify the risk factors associated with the development of chronic pain. ⋯ The Kugel inguinal hernia repair is associated with a low rate of postoperative chronic pain. The minimally invasive preperitoneal approach of the Kugel technique probably causes less nerve damage and subsequent neuropathic pain. Chronic pain seems to be more common in young female patients with immediate postoperative pain.

In Edinburgh a group of surgeons agreed to convert to a lightweight, composite mesh (Ultrapro-Ethicon) for totally extraperitoneal (TEP) inguinal hernia surgery. The aim of this study was to compare the outcome following the use of a new lightweight vs a standard heavyweight mesh during TEP hernia repair. ⋯ In view of increased patient comfort, we continue to recommend LWM for laparoscopic inguinal hernia surgery but would recommend that, in larger hernias and possibly for all, the surgeon should improve mesh adhesion.

Aim of this study was to analyze long-term sequelae, risk factors, and satisfaction after inguinal hernia primary repair. ⋯ This study demonstrates that the main problem after inguinal hernia repair remains chronic pain, which was the primary reason of dissatisfaction. The SF-MPQ is feasible and easy to administer to all patients and provides important information about qualitative features of the pain.
