Rate and Risk Factors of Early Ventriculoperitoneal Shunt Revision: A Five-Year Retrospective Analysis of a Referral Center.

Background: Cerebral shunts are the mainstay treatment of hydrocephalus. Because most previous studies have focused on factors related to long-term outcomes of shunt surgery, we aimed to assess the rates and causes of 30-day ventriculoperitoneal shunt (VPS) failure in a single referral center over 5 years in both adult and pediatric patients.

Methods: Patients who underwent VPS surgery from February 2012 to February 2017 in Ghaem Teaching Hospital, Mashhad, Iran were evaluated retrospectively through clinical history, operative reports, imaging studies, and follow-up notes.

The Comparison of Infusion of Two Different Sedation Regimens with Propofol and Ketamine Combination During Plastic and Reconstructive Surgery.

Objective: Anesthetic agents are often combined to enhance their therapeutic effects while minimizing adverse events. The aim of this study was to evaluate the effects of two different sedation regimens of ketamine and propofol combination via infusion on perioperative variables in patients who underwent plastic and reconstructive surgery.

Methods: This randomized double-blind clinical trial was done on 80 patients who were randomized to two groups; group 1 (n = 40) received a 2:1 mixture of 9 mg/ml propofol and 4.
