Objectives:To investigate the effect of polyester filament fiber surgical drape in neurosurgery.Methods:A total of 181 neurosurgical surgeries were selected from April to July 2019 in a first-class general hospital. They were randomly divided into 2 groups, cotton group (92 cases) were covered with cotton drape, polyester filament fiber group (89 cases) were covered with polyester filament fiber. The anti-permeation performance, incidence of intraoperative hypothermia, and incidence of postoperative surgical site infection (SSI) between the two groups were compared.Results:At the end of the operation, the wetting rate of the cotton draped was 58.7% (54/92) and that in polyester filament fiber was 15.7% (14/89), with statistically significant differences ( χ2 value was 35.605, P<0.05);The incidence of intraoperative hypothermia was 22.8% (21/92) in the cotton group and 11.2% (10/89) in the polyester filament fiber group, with statistically significant differences ( χ2 value was 4.281, P<0.05). The incidence of SSI in the cotton group was 16.3% (15/92) , while that in the polyester filament fiber group was 6.7% (6/89) , with statistically significant differences ( χ2 value was 4.034, P<0.05). Conclusions:In neurosurgical operations with a long operation time and a large amount of irrigation fluid during the operation, using the polyester filament fiber drape can prevent the irrigation fluid from wetting the surgical drape, protect the surgical incision better, reduce the incidence of SSI and intraoperative hypothermia to some extent.

Objective:To construct a dual-track clinical nursing path based on fast and slow channels in Post Anesthesia Care Unit (PACU) to provide references for the implementation of standardized nursing for patients in the anesthesia recovery period.Methods:On the basis of literature review, evidence-based methods were used to construct the classification management of patients in anesthesia recovery period based on the theoretical framework of fast and slow channels. The research team initially drafted the clinical nursing path table in the PACU from May 2019 to June 2019 and conducted two rounds of Delphi expert letter inquiries from July to October 2019 to further revise and improve the path table.Results:The recovery rates of the two rounds of expert consultation were 90.91% and 100.00%. The expert authority coefficient was 0.89, the variation coefficient of the path table was 0.06, and the Kendall harmony coefficient was 0.25. Finally, the flow chart and three levels of anesthesia recovery based on fast and slow channels were formed.Conclusions:The established clinical nursing path in the PACU has reliable results. Based on the fast and slow channels to assess the risk degree of patients in the anesthesia recovery period, the classified management of patients can be implemented in the PACU, providing a reference for clinical nursing practice.

The surgical drape system is a sterile barrier to prevent skin bacteria from entering the incision. The surgical drape system is used to maintain the sterile state of the surgical area, which can reduce the risk of SSI. Therefore, it is the basic measure to prevent SSI. This review summarizes the importance, development, current situation and prospect of surgical drape system, in order to provide reference for clinicians.

Objective To explore the cognitive process of cognitive flexibility in obsessive-compulsive disorder patients. Methods Thirty-two patients with obsessive-compulsive disorder (OCD) and thirty-two healthy controls were included. The Task Switch paradigm and event-related potentials were used to assess cognitive flexibility. Results The accuracy rate was lower in the OCD than in control group in both repeat and switch trials (P＜0.05). Reaction time analysis revealed significant differences in both repeat and switch between the OCD and controls ( P＜0.05). ERPs revealed significant differences in N2 and P3 amplitudes between OCD and controls (P＜0.05). There was no significant correlation between cognitive flexibility (accuracy rate and reaction time of repeat and switch, and N1, N2 and P3 amplitudes) and clinical forced symptoms in OCD (P＞0.05). Conclusion Obsessive-compulsive disorder of cognitive flexibility by injured.

Objective To explore the optimal time for starting to drink plenty of water after 131I treatment in differentiated thyroid carcinoma(DTC) patients.Methods Totally 83 cases of DTC patients were randomly divided into three groups,and started to drink plenty of water at 12 h(group A),24 h(group B),and 36 h(group C) after treatment with 131I therapy.We measured and compared equivalent dose rate using the Inspector Alert gamma ray monitor at 1 meter in front of the patient's abdomen and neck at 6 h,12 h,24 h,36 h,48 h,72 h after taking 131I.We compared the discharge rate at different time and evaluated the curative effect.Results Equivalent dose rate of the abdomen at 24 h and 36 h after treatment and the discharge rate at 36 h and 48 h after treatment among three groups showed significant differences(P＜0.05).There were no statistically significant differences in the curative effect(P＞0.05).Conclusion Starting to drink plenty of water at 12 h after taking 131I can accelerate the decreasing of equivalent dose rate with no influence on the curative effect and improve the discharge rate at early.

Objective To investigate the effects of soft silicone foam dressing on the prevention of intraoperative pressure ulcer in patients undergoing spine surgery. Methods A total of 232 patients were divided into control group and experimental group (116 cases each group) by coin slot method. The control group was treated with conventional pressure ulcer prevention and treatment. The experimental group was treated with conventional intervention measures. Soft silicone foam dressing paste use, the end of surgery to observe the two groups of patients under the chin skin condition. Results In the control group, there were 10 cases at stage I in the lower part of the skin, and 5 cases (4 cases of skin blisters and 1 case of partial cortical absence) at stageⅡ. 2 cases in the experimental group were at stage I; no cases were at stageⅡ, the two groups were no stage Ⅲ and above pressure ulcer occurred in the experimental group under the chin pressure ulcer was significantly lower than the control group, The difference was statistically significant (χ2=10.727, P<0.05). Conclusion Conventional pressure ulcer prevention and control interventions combined with shaped soft silicone foam dressing for skin protection of special parts of chin under prone position surgery is beneficial to prevention of intraoperative pressure ulcers.

Objective To explore the effect of two different core temperature monitoring methods on cardiopulmonary bypass and coagulation function in open heart surgery to provide a reference for monitoring the core body temperature in open heart surgery. Methods One hundred and forty patients undergoing open heart surgery in this hospital from June to December 2016 were divided into the control group(n= 70) and observation group (n= 70). The control group monitored the temperature of nasopharynx and bladder. The observation group monitored the temperature of rectum and nasopharynx. The temperature falling time of cardiopul monary bypass, time of blocking ascending aorta,time of rewarming, total time of cardiopulmonary bypass were recorded during operation. The coagulation function was monitored on 1 d before surgery and at the end of surgery,including thrombolytic time (TT), prothrombin time (PT) and activated partial thromboplastin time (APTT). Results The temperature falling time,rewarming time, total time of cardiopulmonary bypass in the control group were more than those in the observation group, the difference was statistically significant(P<0.01);there was no statistically significant difference in coagulation function indicators(TT,PT,APTT) before operation between the two groups (P> 0.05). At the end of the operation, the coagulation function indicators (TT, PT, APTT) had statistically significant difference between the two groups (P<0.01). The coagulation function indicators in the observation group were better than those in the control group. Conclusion Using the rectal temperature for monitoring the core tempera ture in the patients undergoing open heart surgery under cardiopulmonary bypass is better than using bladder temperature, which can shorten the time of cardiopulmonary bypass and improves coagulation function.

Objective This study aims to investigate the moral disgust cognitive processing of patients with obses?sive-compulsive disorder (OCD) and its relationship with OCD symptoms. Methods Twenty-eight OCD and 30 healthy controls matched for gender, age and education completed lexical decision task, recording reaction time and accuracy of words and assessing the degree of disgust. Yale-Brown obsessive-compulsive scale (Y-BOCS) and Padua Invento?ry-Washington State University Revision (PI-WUSR) were used to assess the symptoms. Results OCD group showed significantly longer reaction time to core disgust-related words [(762.69 ± 128.25) ms vs. (648.69 ± 162.66) ms] and moral disgust-related words [(798.73 ± 115.26) ms vs. (727.00 ± 106.06) ms] than the healthy controls (P<0.05). OCD group showed significantly higher aversion degree to core disgust-related words [(6.38 ± 1.78) vs. (5.03 ± 1.64)] and moral dis?gust-related words [(7.08 ± 1.23) vs. (5.77 ± 1.44)] than control group (P<0.05). Y-BOCS total score, Y-BOCS obsessive thoughts score, Y-BOCS compulsive behavior score, total score of PI-WUSR, cleaning/pollution force factor score, hurt?ing themselves and others force factor were positively correlated with two types of disgust-related words in patients group (P<0.05). Multiple stepwise regression analysis between disgust words and Y-BOCS/PI-WUSR scores pointed that only CWCF influenced disgust degree of core disgust-related words (β=0.61, P<0.01) and moral disgust-related words (β=0.54, P<0.01), respectively. Conclusion The core disgust and moral disgust of OCD are stronger compared to controls.

Objective To identify the effect of SBAR (situation, background, assessment, recom-mendation) in OR (operating room)nursing teaching rounds. Methods According to internship turns, rou-tine group (even number, Group A:68 students) and SBAR group (odd number, Group B:70 students) were chosen by drawing lots. Group A used conventional mode for history report, while Group B used SBAR mode. Students' performance was evaluated by OR nurse students' rounds standard scale and the reporting time was recorded. Each nurse students filled in Communication Self-efficacy Evaluation Form on the fifth week in OR. The information was input into excel. The results of the two groups were compared with SPSS 11, and the data were analyzed by chi square test and t test. Results The average reporting quality score was 16.74 for Group A, and 18.66 for Group B. The average score of Group B was higher than that of Group A. Compared with the cases scores above 18 between the two groups, the result was statistically significant, P=0.039. The average score of communication Self-efficacy in Group A was 42.88, while it was 44.94 in Group B, which showed that Group B had better score than that of Group A. Significant differences was found between the two groups when compared the cases with score above 45, P=0.010. The average reporting time was (2.42±1.16) minutes for Group A and (2.32±1.21) for Group B, and there is no significant differences between the 2 groups. Conclusion SBAR is helpful for improving students communication Self-efficacy, and making progress on nursing round reporting quality,and it is worth promoting in clinical teaching.
