Randomized Controlled Trial
Insertion of the ProSeal laryngeal mask airway is more successful with the 90 degrees rotation technique.
The 90 degrees rotation technique for inserting the ProSeal laryngeal mask airway (PLMA) in anesthetized paralyzed patients was compared with the index finger insertion technique. ⋯ The 90 degrees rotation technique for inserting the PLMA is more successful than the standard index finger insertion technique. It is associated with fewer side effects, such as blood on the PLMA and sore throat, which suggests it causes less pharyngeal trauma.

Randomized Controlled Trial
Orogastric tubes do not improve transesophageal echocardiographic imaging during cardiac surgery: a randomized trial.
Image quality is often an overlooked consideration that affects the quality and findings of a perioperative transesophageal echocardiography (TEE) study. We undertook a study to evaluate the potential benefit of orogastric (OG) tube insertion following tracheal intubation as a method to improve TEE image quality. ⋯ While this study was underpowered to detect small changes in image quality, the use of an OG tube for routine cases did not improve the overall quality of the related images acquired during TEE examination.

Randomized Controlled Trial
Somatic paravertebral block decreases opioid requirements in children undergoing appendectomy.
Somatic paravertebral block (SPVB) appears to provide effective and prolonged nerve block in children; however, study of its use in this population is limited. We compared SPVB with no block in children undergoing appendectomy. ⋯ In children undergoing appendectomy, SPVB provides better pain relief than no block and reduces opioid requirements. Side effects were not statistically different between groups.

Randomized Controlled Trial
Optimal remifentanil dose for laryngeal mask airway insertion when co-administered with a single standard dose of propofol.
This dose-response study aimed to determine the optimal dose of remifentanil combined with propofol 2.5 mg.kg(-1) iv in order to achieve excellent conditions for laryngeal mask airway (LMA) insertion in 95% of adult female patients. ⋯ The required dose of remifentanil is 1.32 (95% CI 0.99-2.46) microg.kg(-1) to achieve excellent LMA insertion conditions in 95% of patients when co-administered with propofol 2.5 mg.kg(-1) in healthy premedicated female patients undergoing elective ambulatory surgery.
