Effects of dexamethasone on local infiltration analgesia in total knee arthroplasty: a randomized controlled trial.

Purpose: Intraoperative local infiltration analgesia has gained increasing popularity in joint replacement surgery. Because there is considerable variation among drug combinations, analgesic effects of each drug are not well understood. The purpose of this study was to clarify the efficacy of the addition of steroid to local anaesthetics in local infiltration analgesia during total knee arthroplasty.

Local infusion analgesia using intra-articular double lumen catheter after total knee arthroplasty: a double blinded randomized control study.

Purpose: Although intra-operative local infiltration analgesia has gained increasing popularity in joint replacement surgery, it is not clear whether postoperative local infusion analgesia using an indwelling catheter provides clinically important additional effects. We, therefore, conducted a randomized controlled trial to clarify the efficacy of the originally developed local infusion analgesia technique in total knee arthroplasty.

Methods: Forty patients were randomly allocated to the local infusion analgesia or control group.

The endoscopically measured effects of airway maneuvers and the lateral position on airway patency in anesthetized children with adenotonsillar hypertrophy.

Obstruction of the upper airway is a major challenge for anesthesiologists administering general anesthesia in spontaneously breathing children with adenotonsillar hypertrophy. Lateral positioning is a simple treatment for obstructive sleep apnea. In this study, we examined the effects of body position shifting and common airway maneuvers such as chin lift and jaw thrust on airway patency (stridor score and upper airway dimensions by endoscopy) in anesthetized children scheduled for adenotonsillectomy.

The effects of chin lift and jaw thrust while in the lateral position on stridor score in anesthetized children with adenotonsillar hypertrophy.

Obstruction of the upper airway is a major challenge for anesthesiologists administering general anesthesia in spontaneously breathing patients, especially in pediatric anesthesia with adenotonsillar hypertrophy. Lateral positioning is a simple treatment for obstructive sleep apnea and also decreases collapsibility of the pharynx in anesthetized adults with obstructive sleep apnea. In this study, we examined the effects of body position shifting and common airway maneuvers, such as chin lift and jaw thrust, on airway patency (stridor score) in anesthetized children scheduled for adenotonsillectomy.
