XXXX Anesthesia Is Associated With Shortened Length of Hospital Stay Following Orthognathic Surgery.

@entity1 @entity196 @entity551
PURPOSE: To evaluate the impact of induced @entity551 anesthesia on length of hospital stay (LOS) for  @entity1 undergoing maxillary Le @entity196 in isolation or in combination with mandibular orthognathic surgery. MATERIALS AND METHODS: A retrospective cohort study design was implemented and @entity1 undergoing a Le @entity196 as a component of orthognathic surgery at the Mayo Clinic from 2010 through 2014 were identified. The primary predictor variable was the presence of induced @entity551 anesthesia during orthognathic surgery. @entity551 anesthesia was defined as at least 10 consecutive minutes of a mean arterial pressure no higher than 60  mmHg documented within the anesthetic record. The primary outcome variable was LOS in hours after completion of orthognathic surgery. The secondary outcome variable was the duration of surgery in hours. Multiple covariates also abstracted included @entity1 age, @entity1 gender, American Society of Anesthesiologists score, complexity of surgical procedure, and volume of intraoperative fluids administered during surgery. Univariable and multivariable models were developed to evaluate associations between the primary predictor variable and covariates relative to the primary and secondary outcome variables. RESULTS: A total of 117 @entity1 were identified undergoing Le Fort I orthognathic surgery in isolation or in combination with mandibular surgery. Induced @entity551 anesthesia was significantly associated with shortened LOS (odds ratio [OR]  = 0.33; 95% confidence interval [CI], 0.12-0.88; P  = .026) relative to @entity1 with normotensive regimens. This association between @entity551 anesthesia and LOS remained statistically significant in a subgroup analysis of 47 @entity1 in whom isolated Le Fort I surgery was performed (OR  = 0.13; 95% CI, 0.03-0.62; P  = .010). Induced @entity551 anesthesia was not statistically associated with shorter duration of surgery. CONCLUSION: Induced @entity551 anesthesia represents a potential factor that minimizes postoperative LOS for @entity1 undergoing routine maxillary orthognathic surgery alone or in combination with mandibular procedures. @entity551 anesthesia does not appear to be effective in minimizing the duration of surgery within this same @entity1 population.
