Objective? To explore the clinical application of information technology in the multidisciplinary chain management of surgical patient handover, in order to reduce the safety hazard in the process of surgical patient handover. Methods? In the contemporary controlled study, 300 patients were selected as the control group from February to July 2017 by cluster sampling, and 303 patients were selected as experimental group from February to July 2018. Traditional sectional handover method was adopted in the control group, to managed the patients＇ handover from each section. In the experimental group, based on the information communication platform between the surgery room and relevant clinical departments, by clinical electronic documents chain transfer method, quality inspection and supervision information feedback technology, to achieve shared decision and improvement of patients handover problems, we built the multidisciplinary management pattern. The two groups were compared for statistical difference from six aspects:the rate of acceptance specification, the accuracy of identity verification method, the rate of operation labeling verification, the accuracy of inventory of items, the evaluation of pipeline patency, and the evaluation of skin condition at the compression site. Results? The rate of standard delivery of surgical patient handover increased from 49.33% to 92.08% in the two groups. The experimental group was better than the control group in the rate of correct delivery of handover from the following five aspects: identity recognition, indication of surgical site, inventory of articles carried, unobstructed pipeline and skin state of the pressure site with statistical significance (P＜ 0.01). Conclusions? The multidisciplinary chain management model of surgical patient handover supported by information technology is effective in clinical application, which can significantly reduce the risk of hazard in patient handover and is worthy of clinical promotion.

Objective? To determine tourniquet pressure based on limb occlusion pressure(LOP) and to explore its effects on laparoscopic surgery in adults. Methods? Totally 200 adult patients who received laparoscopic surgery in a Class Ⅲ Grade A hospital between June and December 2017 were selected by cluster sampling and divided into the control group (n=100) and the observation group (n=100) according to the random number table. The conventional pressure of 450 mmHg (60 kPa) for lower exterminates was applied to the patients in the control group, while the pressure for the patients in the observation group was determined on limb occlusion pressure with the arterial pulse probe in air pressure tourniquet in accordance with the guideline of the Association of Perioperative Registered Nurses (AORN, 2013) and the care guideline for surgical patients using air pressure tourniquet. The surgical vision score, air pressure tourniquet pressure, color of skin at tourniquet cuff and change of skin morphology were observed and recorded. Results? The clearance of surgical vision of the two groups was 86% and 82%, respectively (P＞ 0.05). The pressure of air pressure tourniquet of the observation group was (316.48±20.10) mmHg, while the fixed pressure of the control group was 450 mmHg (P＜0.05). The incidence of cutaneous injury comorbidities in the control group was 65%, while the incidence of postoperative skin injury in the observation group was 20% (P＜ 0.05). Conclusions? The tourniquet pressure determined based on limb occlusion pressure in laparoscopic surgery for adult patients does not affect the vision of surgeons and can effectively reduce the adverse effects of tourniquet used during operation.

Objective: To analyze the effect of variables on both " effective operative time" and " operative turnaround rate" . Methods: Based on the time node data of operation rooms (OR) of a hospital in 2017, SPSS 19.0 statistical software was used to analyze the " effective operative time" and " operative turnover rate" under different condition variables. The methods include mean value, standard deviation and independent sample t test. Results: The mean values of " effective operative time" varied with months (with the highest month of 9.18±2.49 h/d, and the lowest month of 7.93±2.60 h/d), and with workdays as well (the highest on Monday: 8.72±2.57 h/d, and the lowest on Friday: 7.77±2.67 h/d). Meanwhile it also varied with ORs (the highest of 9.92±2.50, and the lowest of 4.84±1.98). In surgeries which started before 8: 30 am, the effective operative time of OR was significantly higher than others. On Mondays, the effective operative time of ORs was the highest, but the operative turnover rate was poor (as low as 13.20%). There was significant difference in the operative turnover rate between specialized ORs and those not for general purpose. Conclusions In order to optimize the comprehensive utilization of operation rooms, it is necessary to coordinate the operations, reduce the proportion of non-planned operations on " Mondays" , raise the turnover rate, and strengthen the coordination between working posts.

Objective To study the effects of perioperative body temperature management on intraperitoneal hyperthermic perfusion chemotherapy patients with abdominal malignant tumor. Methods From June to Decmber 2016, a total of 120 intraperitoneal hyperthermic perfusion chemotherapy patients with abdominal malignant tumor who met the inclusion criteria were recruited and randomly divided into control group and observation group, with 60 cases in each. All the subjects were given routine operation nursing. On the basis of that, the observation group were given perioperative body temperature management. The body temperature, heart rate, pulse pressure and the difference of tumor markers of carcineombryonic antigen (CEA) and carbohydrate antigen19-9(CA199) before and after treatment were compared between the two groups. Results The difference value of temperature, heart rate and pulse pressure between 30 minutes after treatment and before treatment in the observation group were (3.7±0.4)℃, (12.4±2.7)bp/min and (5.6±1.9)mmHg respectively. The fluctuation of vital signs was lower than the control group, and the differences were statistically significant (t=6.062, 14.897, 10.392; P<0.01). The observation group patients' CEA was (52.8±2.4)μg/L, and CA199 was (106.1±5.3)U/ml after treatment, which were both lower than the control group, with statistical differences(t=31.415, 33.803; P< 0.05). Conclusions Perioperative body temperature management could significantly stabilize the body temperature, heart rate and pulse pressure, which could significantly promote intraperitoneal hyperthermic perfusion chemotherapy's curative effect for patient with abdominal malignant tumor.

Objective To evaluate the effect of music therapy in vitrectomy patients under local anesthesia. Methods A total of 200 patients undergoing vitrectomy from September to December 2016 in Union Hospital of Tongji Medical College were recruited by cluster sampling method, and randomly divided into observation group and control group, with 100 cases in each. Routine preoperative visit and intraoperative care were given to the control group. Besides routine care,the observation group was given preoperative personalized music intervention from 10 minutes before the surgery to the end. Vital signs, patients' compliance and pain scores were compared between the two groups. Results The heart rate and systolic blood pressure of the observation group patients were significantly lower than the control group (P< 0.05). While surgery compliance was higher than the control group (P<0.05), and the pain score was lower than the control group (P<0.05). All of the differences were statistically significant. Conclusions Music intervention in perioperative period can effectively improve vitrectomy patients cooperate compliance, and reduce the patients pain score.
