ABSTRACT
Objective:To investigate the effect of nonalcoholic fatty liver disease (NAFLD) on glucose and lipid metabolism during pregnancy.Methods:A retrospective analysis was performed in women who gave birth in Minhang Hospital Affiliated to Fudan University from January 2013 to June 2020. The data on demographic, clinical examination, and delivery were obtained via electronic medical record abstraction. According to the ultrasound imaging, all pregnant women were divided into NAFLD group and control group. The difference of glucose and lipid metabolism indexes, incidence of gestational diabetes mellitus, and gestational hypertension between two groups were compared. Logistic regression model was used to examine potential associations between NAFLD and metabolic related adverse pregnancy outcomes.Results:A total of 14 708 pregnant women with a mean age of (29.1±4.7) years and a mean body mass index of (21.0±2.8) kg/m 2 were included in our study. Of those eligible women, 554 (3.8%) were confirmed by ultrasound as NAFLD. Pregnant women with NAFLD presented higher circulating levels of fasting glucose [(4.2±0.5)mmol/L vs (4.1±0.5)mmol/L, P<0.01], 1 h plasma glucose [(7.4±1.7)mmol/L vs (6.6±1.6)mmol/L, P<0.01] and 2 h plasma glucose [(6.2±1.4)mmol/L vs (5.7±1.3)mmol/L, P<0.01] after glucose loading, HbA 1C [(5.2±0.4)% vs (5.1±0.5)%, P<0.01], triglyceride [(2.1±1.1)mmol/L vs (1.6±0.7)mmol/L, P<0.01], total cholesterol [(4.8±0.8)mmol/L vs (4.7±0.9)mmol/L, P<0.01], low density lipoprotein-cholesterol [(2.6±0.7)mmol/L vs (2.5±0.7)mmol/L, P<0.01], uric acid [(224.1±51.8)μmol/L vs (203.0±45.9)μmol/L, P<0.01] level. After adjusting for potential confounders, NAFLD significantly increased the risk of gestational diabetes mellitus ( OR=1.722, 95% CI 1.079-2.747, P=0.023) and gestational hypertension ( OR=3.845, 95% CI 2.247-6.582, P<0.001). Conclusions:Compared to non NAFLD, women with a diagnosis of NAFLD had more significant glucose and lipid metablic aberrations during pregnancy and increased incidence of gestational diabetes and gestational hypertension. Pregnant women with NAFLD should be closely monitored on glucose and lipid metabolism and blood pressure to prevent gestational diabetes mellitus and hypertension.
ABSTRACT
Objective To evaluate the effect of dexmedetomidine on the quality of recovery from sevoflurane-based anesthesia in the patients undergoing abdominal surgery.Methods Eighty patients of both sexes, aged 30-64 yr, weighing 45-80 kg, with American Society of Anesthesiologists physical status Ⅰ or Ⅱ , scheduled for elective abdominal surgery, were randomly assigned into 2 groups (n =40 each) using a random number table: control group (group C) and dexmedetomidine group (group D).After routine induction of anesthesia, all the patients were tracheally intubated, and mechanically ventilated.Anesthesia was maintained with sevoflurane inhalation and intermittent iv boluses of sufentanil and cisatracurium besylate, and bispectral index values were maintained at 45-60.After induction of anesthesia, dexmedetomidine was infused in a dose of 1 μg/kg over 15 min, followed by a continuous infusion of 0.6 μg · kg-1 · h-1 until 30 min before the end of surgery in group D.Group C received normal saline instead.Heart rate (HR) and mean arterial pressure (MAP) were recorded at the end of surgery, and at 1 min before and after extubation.The emergence time, extubation time, and occurrence of bucking during extubation, and nausea and vomiting, respiratory depression, and agitation during recovery from anesthesia were recorded.Results Compared with group C, MAP and HR were significantly decreased at 1 min before and after extubation, the emergence time and extubation time were shortened, the incidence of bucking, nausea and vomiting, and agitation was decreased, and no significant change was found in the incidence of respiratory depression in group D.Conclusion Dexmedetomidine infused in a dose of 1 μg/kg after routine induction of anesthesia, followed by a continuous infusion of 0.6 μg · kg-1 · h-1 until 30 min before the end of surgery, can significantly increase the quality of recovery from sevoflurane-based anesthesia in the patients undergoing abdominal surgery.
