ABSTRACT
Objective@#To study the effect of intraoperative heating on perioperative hypothermia and complications in laparoscopic surgery.@*Methods@#A total of 126 patients who underwent endoscopic sinus surgery in the general surgery ward of the Fifth People′s Hospital of Dalian from March 2016 to March 2017 were selected. Two population-average hypothesis tests with completely random design were used to generate 126 random tables by computer. The patients were randomly divided into the intervention group and the control group, with 63 cases in each group. In the control group, passive heat preservation was used during the operation. The intervention group was preheated by heating blanket from the time of leaving the ward to the operation bed, and the heating blanket was used to cover the lower limbs during the operation. The demographics of all patients at admission and preoperation, after surgery were recorded. The statistical differences between the two groups were compared.@*Results@#The core temperatures of the intervention group 120, 180, 240, 300, and 400 min after anesthesia were (35.6 ± 1.3), (35.7 ± 1.6), (35.5 ± 1.4), (35.4 ± 1.3), and (35.7 ± 1.1) °C, respectively. Those in the control group were (35.0±1.2), (34.9±1.1), (34.7±1.1), (34.4±1.1), and (34.3±1.1)°C, respectively. The difference between the two groups was statistically significant (t=1.23- 4.32, P<0.05). The amount of intraoperative blood loss in the intervention group and the time required for the postoperative core body temperature to return to 36 °C, pain score after surgery were (98.0±52.6) ml, (40.1±28.3) min, 5.1±4.2, and (167.2 ± 52.6) ml, (98.1 ± 47.3) min, 6.7 ± 4.1 in the control group. The difference was statistically significant (t=2.34, 7.87, 4.56, P<0.05 or 0.01). The incidence of no significant tremor was 65.8% (41/63) in the intervention group, 12.7% (8/63) in the electrocardiogram, and 12.7% (8/63) in the face and neck. The incidence of visible tremor in the trunk was 9.5% (6/63), and the incidence of systemic tremor was 0. In the control group, they were 38.1% (24/63), 20.6% (13/63), and 15.9% (10/63), 20.6% (13/63), 4.8% (3/63). There were statistical differences between the two groups (χ2=3.45, P<0.05).@*Conclusion@#Intraoperative heating can increase the core temperature of patients undergoing laparoscopic surgery and reduce bleeding and complications.
ABSTRACT
Objective: To study the change of placental corticotropin releasing hormone level in pregnant women entering spontaneous labor at term and preterm or posterm,and to investigate the value of CRH as an indicator of preterm labor. Methods: Subjects( n =200) were recruited to the study at their antenatal visits,and plasma samples were obtained at their routine antental clinic visits from 28 weeks to parturition at 2 weeks intervals.CRH were measured by radioimmunoassay. Results: CRH concentrations rose significantly as pregnancy developed and reached the highest level at delivery. Plasma CRH levels were significantly higher in preterm labor and lower in postterm labor after gestational 28 weeks( P
