Effect of room temperature irrigating fluid in the perioperative period of transurethral resection of prostate / 中国基层医药

ABSTRACT

Objective To compare the effects of the different temperature of lavage fluid on the vital signs of the patients during the perioperative period of transurethral resection of prostate (TURP). Methods From June 2016 to June 2017,56 patients received TURP treatment in the First People's Hospital of Linhai were randomly selected. The patients were divided into the observation group and the control group by the random number method, with 28 cases in each group. All patients underwent TURP under continuous epidural anesthesia. The lavage fluid of the observation group was heated and kept at 37℃ . In the control group,the lavage fluid was not heated,the temperature was about 21℃ . The related indicators between the two groups were compared. The changes of 30min,45min and 60min mean arterial pressure (MAP),heart rate (HP),body temperature (T) and blood oxygen saturation (SaO2) in the two groups were observed before and during operation,and the hypothermia in two groups was compared. Results There were no statistically significant differences in the operation time,dosage of lavage fluid,weight of the resection of prostate tissue and amount of bleeding during the operation between the two groups(all P > 0. 05). At preoperation and intraoperative 30min,there were no statistically significant differences in MAP,HP,T,SaO2 between the two groups. At intraoperative 45min,60min,MAP levels in the observation group were (92. 14 ± 8. 63) mmHg, (92. 06 ± 8. 19) mmHg,respectively,which were significantly higher than those in the control group [(85. 33 ± 9. 01)mmHg,(79. 26 ± 9. 84)mmHg] (P < 0. 05). At intraoperative 45min,60min,the HR in the observation group were (79. 45 ± 8. 64) / min,(79. 50 ± 9. 06) / min,respectively,which were significantly higher than those in the control group [(72. 47 ± 8. 21) / min,(65. 44 ± 7. 10) / min] (all P < 0. 05). At intraoperative 45min,60min,T in the observation group were (36. 42 ± 0. 16)℃ ,(36. 12 ± 0. 20)℃ ,respectively,which were significantly higher than those in the control group [(36. 40 ± 0. 14)℃ ,(35. 84 ± 0. 23)℃ ] (P < 0. 05),but SaO2 had no statistically signif-icant difference between the two groups(P > 0. 05). The incidence rates of low temperature,induced arrhythmia in the observation group were 3. 57％ ,0. 00％ ,respectively,which were significantly lower than those in the control group (35. 71％ ,25. 00％ )(χ2 = 7. 240,P = 0. 007;χ2 = 5. 878,P = 0. 015). The incidence rates of low temperature, induced arrhythmia of patients over 75 years old in the observation group were 5. 26％ ,0. 00％ ,respectively,which were significantly lower than those in the control group(44. 44％ ,33. 33％ ) (χ2 = 4. 766,P = 0. 029,χ2 = 4. 667, P = 0. 031). Conclusion The irrigating solution maintained at room temperature can significantly improve the vital signs,reduce hypothermia and induced arrhythmia in patients.
