To investigate the effect of warm water on the high-risk elderly patients undergoing transurethral plasmakinetic resection of the prostate(PKRP).

From October 2019 to March 2020, The clinical data of 60 high-risk elderly patients undergoing PKRP of the prostate with plasma electrotomy were analyzed retrospectively. According to the temperature of bladder irrigation fluid during operation, all patients were divided into warm water group (30 cases) and normal temperature group (30 cases). The anesthesia methods were combined with lumbar and hard anesthesia. In the normal temperature group, the average of age was 71.9 years, medical history was 6.5 years, the prostate volume was 76.5 ml, and the residual urine was 81.2 ml. In the warm water group, the average of age was 75.4 years, medical history was 6.7 years, the prostate volume was 68.7 ml, and the residual urine was 78.4 ml. The vital signs, intraoperative and postoperative tremor incidence, postoperative body temperature drop, intraoperative transient hypotension, and postoperative bladder spasm were compared.

There were no significant differences in baseline data such as age, prostate volume, and operation time between the two groups (P>0.05). The incidences of intraoperative chills in the warm water group and the normal temperature group were 3.3%, 20.0%, respectively, and the average postoperative temperature drop (1.0±0.2)℃, (1.7± 0.5)℃, the incidence of bladder spasm 13.33%, 40.0%, postoperative hospital stay (3.5±0.6) d, were lower than the normal temperature group (5.5±0.8) d, the differences were statistically significant (P<0.05). The changes of vital signs before and after the operation in the experimental group were not statistically significant (P>0.05), and the changes of vital signs before and after the operation in the control group were significant (P<0.001).

In the high-risk patients of PKRP, the use of 37℃ warm saline for bladder irrigation can reduce the fluctuation of vital signs and the incidence of perioperative complications, which is conducive to the rapid recovery of patients after surgery.
