Randomized Controlled TrialPreventing Spinal Hypotension During Cesarean Birth With Two Initial Boluses of Norepinephrine in Chinese Parturients: A Randomized, Double-Blind, Controlled Trial.
Norepinephrine is effective in preventing spinal hypotension during cesarean birth; however, an optimal regimen has not been determined. We hypothesized that an initial bolus of norepinephrine improves efficacy of spinal hypotension prophylaxis beyond continuous norepinephrine alone. ⋯ With a fixed-rate norepinephrine infusion of 0.05 μg·kg -1 ·min -1 , the 0.10 μg/kg initial bolus was more effective in reducing the incidence of spinal hypotension compared with the 0.05 μg/kg initial bolus.

Efficacy of Presurgical Interventions to Promote Smoking Cessation: A Systematic Review.
The aim of this study was to evaluate the efficacy of presurgical interventions for promoting smoking cessation in terms of achieving smoking abstinence and reducing surgical complication rates. A systematic review of randomized clinical trials (RCTs) published from March 2009 to April 2021 was performed following the PRISMA guidelines. References were found in MEDLINE (via PubMed), Web of Science (WOS), and Cumulative Index to Nursing and Allied Health Literature (CINAHL). ⋯ Two multicomponent interventions obtained significant improvements regarding the reduction of short-term postoperative surgical complications. In conclusion, presurgical multicomponent smoking cessation interventions are more effective than brief interventions in terms of achieving abstinence and reducing surgical complications. The follow-up time and the intensity of the interventions were predictors of dropout.
