Comparing the effect of ropivacaine peritonsillar injection before and after adenotonsillectomy on postoperative pain among pediatric patients: A double-blind randomized clinical trial.

Objectives: Ropivacaine local injection is a preventative management option for post-adenotonsillectomy pain. The effectiveness of this approach varies depending on the time of drug administration. This study is aimed to evaluate pre-emptive effect of administration of Ropivacaine before vs.

The effect of post-anesthetic administration of dexmedetomidine versus remifentanil on postoperative agitation of strabismus surgery in children: a randomized double-blind clinical trial.

: Postoperative agitation is a common complication of sevoflurane anesthesia in children and might lead to self-harm and recovery disruption. This study aimed to compare the prophylactic effect of dexmedetomidine and remifentanil on postoperative agitation after anesthesia with sevoflurane. : In this clinical trial, 60 children aged 2 to 7 years with ASA class І, II, candidates for elective strabismus surgery, were randomly assigned to three groups using block randomization.

Reduced preoperative serum choline esterase levels and fecal peritoneal contamination as potential predictors for the leakage of intestinal sutures after source control in secondary peritonitis.

Background: The high rate of stoma placement during emergency laparotomy for secondary peritonitis is a paradigm in need of change in the current fast-track surgical setting. Despite growing evidence for the feasibility of primary bowel reconstruction in a peritonitic environment, little data substantiate a surgeons' choice between a stoma and an anastomosis. The aim of this retrospective analysis is to identify pre- and intraoperative parameters that predict the leakage risk for enteric sutures placed during source control surgery (SCS) for secondary peritonitis.

Touchless underwater wall-distance sensing via active proprioception of a robotic flapper.

In this work, we explored a bioinspired method for underwater object sensing based on active proprioception. We investigated whether the fluid flows generated by a robotic flapper, while interacting with an underwater wall, can encode the distance information between the wall and the flapper, and how to decode this information using the proprioception within the flapper. Such touchless wall-distance sensing is enabled by the active motion of a flapping plate, which injects self-generated flow to the fluid environment, thus representing a form of active sensing.
