Purpose: The purpose of this study was to explore the effect of glove changing during surgery for colon cancer on reducing the degree of contamination of surgical gloves. Methods: The randomized posttest control group design was used. Total 72 surgeries of colon cancer in the K University Hospital in Seoul performed by the team of A-Surgeon and B-Scrub nurse were randomly assigned to one of the three groups. Glove changing with single-gloved state was implemented in the Experimental Group I and outer glove changing with double-gloved state was executed in the Experimental Group II. Single-gloved state was carried in the Control Group. Following the surgical procedure, specimens for bacterial culture were collected the from scrub nurse's gloves to compare the degree of contamination among the three groups. Data were analyzed with One-way ANOVA and the Scheff$\acute{e}$'s multiple comparison test. Results: The degrees of contamination of the Experimental Group I and II were significantly lower than that of the Control Group. There was no significant difference between Experimental Group I and II. Conclusion: Glove changing during surgery with either single or double-gloved state is effective in reducing the degree of contamination of surgical gloves, therefore these methods should be utilized in clinical practice.

Recently, the clinical applications of the autogenous cancellous bone from the proximal tibial metaphysis show satisfactory results in the repair of maxillofacial bony defect or deformity. The proximal tibia has the potential to yield viable cancellous bone with a minimum of morbidity. The purpose of this study was to investigate the regeneration of a full thickness proximal tibial bone defect with covering or uncovering of cortical bone. The follow-up periods were 4, 8, and 12 weeks. Bone defect of right side was uncovered and left side was covered with cortical bone. In the experimental group (uncovered cortical bone) at 12 weeks, the inside of defect was filled to normal marrow tissue. The cortical bone defect was united of inner, outer callus at 4, 8 weeks in both study group. At 12 weeks, the cortical bone defect was remodeled and invaded by osteoclast (giant cell) in experimental group. In the experimental specimen at 12 weeks, the regenerating tissue of bone defect was not differ from the control group.

Rats and mice are commonly used in experimental laboratories and anesthetic drugs are important for researchers to understand the details. Administration of fluids helps to stabilize the experimental animals before anesthesia via intravenously through the lateral vein in rats and in case of difficulty in catheterization and maintenance, fluids are usually administered as boluses. Large volumes of cool fluids will rapidly lead to hypothermia and all parenteral fluids must be warmed to body temperature before administration. Premedication with a sedative may ease induction with volatile anesthetic drugs. The first choice for rodent anesthesia is complete inhalational anesthesia. The second option is using injectable anesthesia. Recovery from the volatile agents that have been used rapid when the agent is no longer administered. Anesthetic monitoring equipment is an infant-size bell sthethoscope that can be used to ausculate the heart and lungs. Supplemental heating should be provided to reduce the heat loss supply and maintain core body temperature. The kinds of drugs, characteristics, route of administration and care after surgery were reviewed and summarized from the references. Anesthetic drugs, maintenance, monitoring and aftercare are important in the laboratories to keep the animal safe in all experimental procedures.

Purpose: The study was aimed to investigate the effects of warm fluid used during surgery on the patients' hypothermia prophylaxis and recovery after surgery. Methods: This data were collected from Jul. 13 to Nov. 31. 2009 at S hospital in M City. 60 patients who met the selection criteria were recruited in the study and divided into two groups. The warmed fluids were used for 30 patients in the experimental group, and the fluids in room air temperature were used for the others in the control group. Collected data were statistically analyzed using SPSS/win 18.0. Results: The body temperatures of the control group were significantly lower during surgery than those of the experimental group (p<.001). Shivering was significantly less occurred in the experimental group than the control group (p=.018). The experimental group used warmed fluids recovered faster than the control group. Conclusion: Warming fluid for the patients with general anesthesia was revealed to be effective in decreasing hypothermia during surgery, reducing shivering, helping recovery from the anesthesia. Further research is warranted to refine and apply this evidence in nursing practice.

Purpose: The purpose of this study was to identify the effects of exhalation breathing exercises using expirometer and that of inhalation breathing exercises using incentive spirometry on pulmonary function and complications in elderly patients with upper-abdominal surgery. Methods: The research design was a nonequivalent control group non-synchronized design. Participants were 63 patients who underwent upper-abdominal surgery under general anesthesia (32 in experiment group, 31 in control group). They were recruited at P university hospital from August 1 to November 30, 2015. Effects were evaluated by measuring pulmonary functions (Forced Vital Capacity [FVC], Forced Expiratory Volume in 1 second [FEV1]) and pulmonary complications. Data were analyzed using SPSS/WIN 18.0 program. Results: There was no difference in FVC between the experimental group and the control group, but FEV1 in the experimental group increased significantly compared to the control group by time change (p=.001). Also, there were no pulmonary complications in the experimental group but there were 5 cases (16.1%)(p=.018) in the control group. Conclusion: Findings indicate that exhalation breathing exercises by elderly patients following upper-abdominal surgery is an effective nursing intervention in enhancing pulmonary function and preventing pulmonary complications.

The purposes of this study were to assess the effect of therapeutic exercise and to offer an approach to the physical therapy and rehabilitation procedure of the temporomandibular joint (TMJ) following surgery. In this research, 42 patients with TMJ surgery were assigned one of two groups. The experimental group included 21 patients who performed therapeutic exercise, and the control group included 21 patients who did not perform therapeutic exercise. Conservative therapy such as an ice pack, a hot pack, and pulsed ultrasound was applied to both groups. Treatment was applied twice a day during the admission period and, after discharge, everyday for six weeks. Visual analogue scale (VAS), incisal biting force, and joint ROM were measured before surgery and at 30 days after surgery. The results were as follows: VAS (p<0.05), mouth opening (p<0.01), lateral excursion to unaffected side (p<0.05), and protrusion (p<0.05) between experimental group and control group showed statistically significant differences. Incisal biting force and lateral excursion to affected side between experimental group and control group showed no statistically significant difference.

Purpose: The purpose of this study was to compare the effects of hand massage provided with different intervals and periods on pain and sleep disturbance after orthopedic surgery. Methods: A non-equivalent control group pretest- posttest design was used. The subjects were admitted in an orthopedic hospital to get a surgery. They were divided into three groups. Group I (n=30) had hand massage every day. Group II (n=30) had hand massage every other day. Control group (n=31) had usual care. Data of all three groups were collected on the day before operation, POD (postoperative day) 6 and POD12. Hand massage was given for 2 and half minutes per hand. Results: Pain on POD6 of experimental group II was reduced more than those of control group. Pains on POD12 of both experimental groups were reduced more than those of control group. On POD6, only perceived sleep disturbance (PSD) was significantly different among groups. On POD12, PSD, total sleeping time, and sleep efficiency were more improved in the experimental groups. Conclusion: Hand massage was effective on the reduction of pain and sleep disturbance after orthopedic surgery. Applying hand massage on alternate day was effective enough. Also the effects were more obvious after 12 days.

Open reduction and rigid internal fixation is the most popular treatment method for maxillofacial fracture patients, and it is unevitable that postoperative pain can be developed. Many surgeons including oral & maxillofacial surgeons have made constant efforts to decrease postoperative pain. This study is a comparison of postoperative analgesia and intramuscular analgesia in patients with mandibular fractures. In this study, twenty-one patients (Experimental group) were randomly selected and they were injected with IV patient-controlled analgesia (PCA; Walkmed$^{(R)}$, USA). For control group another twenty-one patients were injected with intramusclar non-steroid anti-inflammatory drugs (Rheoma$^{(R)}$, Samsung Pharm. Co.). And then, we measured visual analogue scale (VAS) scores from first postoperative day to second day at regular time interval. The following results were uptained; 1. In patient group who with open reduction and rigid internal fixation, there was significant difference of postoperative analgesic effect during the first postoperative day(p<0.05). 2. In patient group with over 90 minutes surgery time, there was significant difference of postoperative analgesic effect during the first and second postoperative day when compared between experimental group and control group(p<0.05). 3. In patient group with less than 90 minutes surgery time, there was no significant difference of postoperative analgesic effect during the first and second postoperative day when compared between experimental group and control group(p>0.05). 4. In patient group with surgery of open reduction using rigid internal fixation at single fractured site, there was no significant difference of postoperative analgesic effect during the first and second postoperative day when compared between experimental group and control group(p>0.05). 5. In patient group with surgery at two fractured sites, there was significant difference of postoperative analgesic effect during the first postoperative day when compared between experimental group and control group(p<0.05). As mentioned above, it suggest that patient-controlled analgesia is more effective for postoperative pain relief than intramuscular injection in patients with rigid internal fixation by open reduction after mandibular fracture occurred. Especially, it is considered that in patient with more than 90 minutes surgery time or in cases with multiple fractured sites had more effective results with PCA therapy than conventional intramuscular analgesics.

Background: Studies on the pain have been dealing with many different ways for last several centuries. Especially, preemptive analgesia is being used as a method to control the postoperative pain. Many studies on its efficacy have been processed in different ways about various drugs, administration methods and times for various operations. And the value of preemptive analgesia are still controversial regarding the results of other clinical studies. The authors performed a clinical study on efficacy of preemptive analgesia using an non-steroidal anti-inflammatory drug (NSAID) for the surgical extraction of impacted third molar teeth and present the more effective pain treatment after oral surgery with literature review. Methods: Using a randomized double blind test design, this study compared the analgesic efficacies of an NSAID, Talniflumate 370 mg. This drug administrated first either 1 hour preoperatively (experimental group) or when the pain developed moderately to severely over 5 scale of verbal rating scales (0-10) to respective 30 patients undergoing the removal of impacted third molars. Pain intensity and the time from the end of surgery were assessed postoperatively whenever the patients demanded additional drug over 5 scale for forty eight hours using same verbal rating scales. Results: The sex distribution, the age of the patients. and the time required for surgery in two groups were similar. The average first time for demanding additional drug after surgery was 163.9 minutes in experimental group and 191.5 minutes in control group. At this time, the average pain intensity was 5.8 in experimental group and 6.1 in control group. And the average second time for demanding additional drug was 365.5 minutes in experimental group and 351.8 minutes in control group. At this time. the average pain intensities were 6.6 in experimental group and 6.2 in control group. No statistically significant difference was found between the average first times and second times, and the average pain intensities at first and second times in two groups. Conclusions: From these results the efficacy of preemptive analgesia used in this study was not appeared. This clinical study indicates that many NSAIDs administrated preoperatively in present practices have weak efficacy of preemptive analgesia for postoperative pain, thus the authors recommend that only postoperative analgesics are adequate without preoperative use of analgesics.
