Analysis of effects of obesity on respiratory recovery after anesthesia / 中国基层医药

ABSTRACT

Objective To observe the respiratory system adverse drug reaction ( AREs) in obese patients in anesthesia recovery incidence and treatment outcome .Methods This was a control prospective trial .Study was con-ducted on 27 cases of obesity and the same amount of normal with body mass index (BMI)<30(control group).The sex distribution ,age and the type of operation and operation was similar between the two groups .The hospitalization rate of AREs in PACU was observed .Descriptive analysis on the variables ,use Mann-Whitney U,compared with chi square test and Fisher exact test of variables .The relationship between variables and AREs was studied by using uni-variate and multivariate Logistic retrospective analysis .Results Obese patients with the STOP-Bang≥3 ( 89% vs 11%,P<0.001)occur more frequently,obese patients had a lower rate of underwent high risk operations (7% vs 41%,P=0.005) and big operation (4% v s15%,P=0.008).Obesity in PACU patients were more susceptible to getting AREs(33% vs 7%,P<0.018).Multivariate analysis indicated that obesity and residual muscle relaxation effect was the independent risk factors of AREs .Obese patients in PACU had a longer periods of time treatment (120min vs 84min,P<0.001).Conclusion Obesity is an independent risk factor for PACU in patients with AREs . Obese patients in PACU were treated time more longer .
