OBJECTIVE: Probe into the causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children. METHOD: The methods of retrospective analysis the difference of postoperative bleeding time and bleeding rate between tonsillectomy by the low temperature plasma and the traditional cold surgical devices in 2-14 years old children. Plasma group contained the tonsillectomy by low temperature plasma between the March in 2012 to the August in 2013. Traditional group contained the tonsillectomy by traditional cold surgical devices between the March in 2005 to the August in 2006. RESULT: In the 1,000 cases of plasma group, 19 cases occurred postoperative hemorrhage, the hemorrhage rate was 1. 9%. Four cases occurred postoperative primary hemorrhage in 8 hours after operation, the postoperative primary hemorrhage rate was 0. 4%. Fifteen cases occurred postoperative delayed hemorrhage, the delayed hemorrhage rate was 1. 50%, the bleeding time was 2-13 days after operation, the average number was 7. 5 days. Nine cases had wound infection and 6 cases had eaten some food improperly in these 15 cases. And in these eaten improperly cases, 4 children had eaten fruit and hard food, 2 children had eaten a little food who lost their weight. In 860 cases of the traditional group, 29 cases occurred postoperative hemorrhage, the hemorrhage rate was 3. 37%. 26 cases occurred postoperative primary hemorrhage in 8 hours after operation, the postoperative primary hemorrhage rate was 3. 02%. Three cases occurred postoperative delayed hemorrhage, the delayed hemorrhage rate was 0. 35%, the bleeding time was 2-6 days, the average number was 4 days. CONCLUSION It is preferable for chileren to having low temperature plasma tonsillectomy. The causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children are probably related to the postoperative infection, the differences of operation skills, the method of stop bleeding, eating the wrong foods, irritating cough, improper nursing and so on.

Objective To evaluate the role of cardiopulmonary coupling (CPC) analysis in evaluating the sleep quality of patients with Parkinson's disease (PD),and explore its correlation with subjective complaints in patients with PD.Methods Sixty patients with PD,admitted to our hospital from October 2015 to December 2017,and 45 healthy controls accepted physical examinations were enrolled.The sleep qualities of all subjects were assessed using CPC and Pittsburgh sleep quality index (PSQI).Independent-sample t test was used to compare the CPC variables and PSQI results,and the correlations between CPC variables and PSQI results were analyzed.Results (1) High-frequency coupling (HFC) and sleep efficiency of PD patients were significantly lower than those of healthy controls (P＜0.05);very low-frequency coupling and sleep latency of PD patients were significantly higher than those of healthy controls (P＜0.05).(2) Results of PSQI in the PD patients were significantly increased as compared with those in the control group (P＜0.05);there was a negative correlation between PSQI results and HFC ratio in the PD group (r=-0.391,P=0.002).Conclusion CPC analysis is effective in reflecting the subjective sleep quality of PD patients and can be used as a new technology in sleep monitoring.
