Effect of heat preservation on the recovery of BIS and the concentration of propofol in the recovery of propofol in elderly patients
Objective To analyze and discuss the effect of heat preservation on the recovery time of BIS and the concentration of propofol in the recovery period of the elderly patients with general anesthesia in order to provide guidance for clinical treatment.Methods 78 elderly patients with general anesthesia were selected as the subjects, and the patients were divided into the control group and the study group with 39 cases in each group.The patients were divided into the control group and the study group.Control group, only to be liquid input and covered by drapes, research group take liquid input and peritoneal flushing fluid heating and heating blanket coverage of insulation measures, were recorded and compared between the two groups from anesthesia began to operation to complete the different time points of esophageal temperature and MAP, and to observe the recovery time of patients and effect compartment concentration differences.Results Two groups at T0, T1 esophageal temperature no significant difference, study group T2-T6 esophageal temperatures were significantly higher than those of the control group (P<0.05), maps of the other two groups at different time points had no significant difference;when two groups of patients with propofol withdrawal BIS values had no significant difference, and in the time of discontinuation BIS is more than or equal to 80 recovery time and effect compartment concentration have significant difference (P<0.05).Conclusion The surgical treatment of elderly patients with general anesthesia can help maintain the body temperature, shorten the recovery time of BIS and reduce the concentration of propofol in the recovery period.
