Meta AnalysisEfficacy and safety of oral versus intranasal midazolam as premedication in children: a systematic review and meta-analysis.
Midazolam hydrochloride is a widely accepted benzodiazepine for premedication in pediatric patients. However, there is no consistent conclusion regarding which route of administration is best. We performed a meta-analysis to assess the efficacy and safety of oral versus intranasal midazolam premedication in children. ⋯ Differences between intranasal and oral midazolam in satisfactory mask acceptance for induction, satisfactory sedation at separation from parents, and postoperative recovery time were not significant. Intranasal midazolam premedication was associated with shorter onset time and higher incidence of nasal irritation.

Observational StudyHydrocortisone may act through the angiotensin II receptor-2 level in patients with catecholamine-resistant septic shock.
This study aimed to compare the serum angiotensin II and its receptor levels (AT1, AT2) in septic patients with catecholamine-responsive or resistant. The effect of hydrocortisone treatment on angiotensin II levels in the catecholamine-resistant septic patients was evaluated. ⋯ It was concluded that angiotensin II and AT1 can be used as a biomarker of refractory septic shock and hydrocortisone may provide their blood pressure correcting effect by reducing AT2 level in these patients. AT2 can be a therapeutic target in the catecholamine-resistant septic shock patients.

Randomized Controlled TrialUse of a curved needle to facilitate four-in-one nerve block performance after total knee arthroplasty in elderly patients: a randomized clinical trial.
Peripheral nerve block is the main analgesic technique for total knee arthroplasty (TKA) in elderly patients. Accurate delivery of the needle tip to the target nerve under ultrasound-guided is a prerequisite for successful nerve block. Failed needle-tip positioning in sciatic nerve (SN) or medial femoral cutaneous nerve (MFCN) block can be due to anatomical structure shadow. The aim of the study was to compare curved and straight needles in regard to the time needed to perform the nerve block for TKA in elderly patients. ⋯ The use of a curved needle can reduce the time required to perform the nerve block, with reduction in the number of attempts and needle redirections. Curved needle also resulted in lesser procedural pain and higher satisfaction compared with the straight needle.
