BACKGROUND: It is one of anesthesiologist's important tasks to know the accurate recovery state of a patient after general anesthesia. Postanesthetic recovery score (PARS) has been widely used as a measure of evaluating recovery state because it is simple, easy to apply and applicapable to all situations. In this study, we investigated whether there were correlations between PARS and PAR-stay time, and examined factors influencing PAR-stay time. METHODS: Two hundreds and five patients were selected randomly. PARS was measured in each patient immediately after he or she arrived at PAR. Correlations between PARS and PAR-stay time were studied. And other variables such as age, sex, physical status, operation site and anesthetic time were studied as influencing factors on PAR-stay time. RESULTS: There were no significant correlations between PARS and PAR-stay time. PARS was influenced by the operation site only. And PAR-stay time was influenced by the patient's age only. CONCLUSIONS: In evaluating the postanesthetic recovery state, it seems to be important to consider not only PARS but also other factors such as patient's age.

BACKGROUND: This study was doned to evaluate the rate of awakening after desflurane or isoflurane anesthesia in pediatric tonsillectomy patients. METHODS: Sixty patients, aged 5 10 years undergoing a tonsillectomy with or without an adenoidectomy were randomly assigned to receive either desflurane-N2O (group D) or isoflurane-N2O (group I). A recovery profile was assessed by a 3 point scale for the first 0, 15 and 30 min in the recovery room. RESULTS: It was statistically significant that group D had a shorter extubation time and eye opening time and a less apprehensive score than group I at 0, 15 and 30 min. CONCLUSIONS: We conclude that desflurane-N2O may offer clinical advantages over isoflurane when used for maintenance of anesthesia during a pediatric tonsillectomy.

PURPOSE: The purpose of this study was to identify factors associated with performance of nursing care for postoperative delirium of elderly patients among recovery room nurses. METHODS: The research was a cross-sectional, descriptive design using questionnaires. The participants were 99 nurses from five urban recovery rooms. Data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with SPSS WIN 21.0. RESULTS: The performance level of delirium nursing care was low because its mean score was 3.80 out of 5. Performance of nursing care was significantly positively correlated with the importance of nursing care and self-efficacy. Stepwise multiple regression analysis for performance of nursing care revealed that the most powerful predictor was the importance of nursing care. The importance of nursing care and self-efficacy explained 32.3% of the variance. CONCLUSION: The results indicate a need to enhance the performance of nursing care for postoperative delirium of elderly patients among recovery room nurses. The findings also suggest that consideration be given to strategies for improving the importance of nursing care and self-efficacy in developing programs to enhance the performance level of nursing care for elderly patients with postoperative delirium.

BACKGROUND: The pain caused by injection of propofol is known to be related to the concentration of aqueous free propofol. Microemulsion propofol can cause a serious pain because it has 7 times higher concentration of aqueous free propofol. We used ondansetron, lidocaine, ondansetron lidocaine as pretreatment to compare the effect for injection pain of microemulsion propofol. METHODS: 75 patients, ASA physical status I or II were enrolled. We randomly allocated into Group L (n = 25) received 2% lidocaine 40 mg, group O (n = 25) received ondansetron 4 mg and group M (n = 25) received ondansetron 4 mg plus 2% lidocaine 40 mg as pretreatment. After instituting standard monitoring, the venous drainage was occluded using a pneumatic tourniquet at 25 cm proximal to venous line. The patients were pretreated over a period of 15 seconds with one of the pretreatment drug. After releasing the tourniquet, microemulsion propofol was injected. We asked the patient about degree of injection pain until loss of consciousness, by using 0-100 point pain intensity numerical rating scale (PI-NRS). In the recovery room, we asked the patient whether they recall injection pain. RESULTS: There were significant differences in the group L and the group M compared with group O on PI-NRS (P < 0.05). The incidence of injection pain was significantly lower in group L and group M than group O. CONCLUSIONS: Pretreatment of lidocaine and lidocaine + ondansetron is more effective than ondansetron alone for reducing pain on injection of microemulsion propofol.

PURPOSE: This study was conducted to compare the effects of simulation-based training on knowledge, self-efficacy and clinical performance, underwent before or after the clinical practice for the nursing students. METHOD: A comparison group design was established with pre-clinical practice group (n=34) and post-clinical practice group (n=34). Both groups participated in simulation-based training before or after the clinical practice at the recovery room. Chi-square test, t-test and paired t-test were performed to analyze the data. RESULTS: Both groups showed significantly higher post-test scores in knowledge and self-efficacy than pre-test scores (p<.001). The group with simulation training performed before their clinical practice (pre-clinical practice group) showed significantly higher self-efficacy (p=.044) than the group with simulation training done after their clinical practice (post-clinical practice group). However, there was no significant difference in the knowledge (p=.922) and clinical performance (p=.887). CONCLUSION: These findings of the study suggest that simulation based training in pre-clinical practice is effective to enhance the self-efficacy and to improve knowledge and clinical performance of the nursing students.

BACKGROUND: Tramadol is a centrally acting analgesic with weak opioid agonist properties and has effect on the spinal inhibition of pain. This study was designed to evaluate the efficacy of tramadol in the treatment of postanesthetic shivering. METHODS: Sixty patients (ASA class I/II) who showed postanesthetic shivering were randomly assigned into three groups (n=20): Normal saline group; normal saline 10 ml, tramadol (TRD) 0.5 mg/kg group; tramadol 0.5 mg/kg, TRD 1.0 mg/kg group; tramadol 1.0 mg/kg. And all patients received standard postoperative management in the recovery room. Evaluation of the grade of shivering was done at 30 seconds, 2, 5 and 10 minutes from the beginning of the treatment by the same investigator who had injected the drug. The age, sex, weight, duration of anesthesia and axillary temperature were recorded. RESULTS: By 30 seconds, 2 minutes, 5 minutes, and 10 minutes, 0, 4, 9, 9 patients of the 0.5 mg/kg tramadol group (n=20) and 7, 18, 19, 19 patients of the 1.0 mg/kg tramadol group (n=20) stopped the shivering respectively. But in 3 patients of 0.5 mg/kg tramadol group who stopped shivering by 5 minutes, shivering was recurred within 10 minutes and in 3 patients who had not stopped shivering by 5 minutes, shivering stopped by 10 minutes. In the placebo group, only 1 patient stopped shivering by 5 minutes. CONCLUSION: 1.0 mg/kg of tramadol was effective for the treatment of postanesthetic shivering but 0.5 mg/kg of tramadol was ineffective.

BACKGROUND: The operating room should provide an optimum environment that is safe for the patient and the working personnel. In this point of view, we investigated 8 items of temperature, humidity, air flow, noise, brightness, dust, CO2 and NO2. METHODS: Operating rooms, corridors and recovery rooms were tied as region I, II and III depending on their characteristics. 29 points were measured using appropriate instruments. After that, averaged values were calculated. RESULTS: Indoor climate (temperature, humidity and air flow) in region I were averaged 24.7, 65, 0.18/II were 25.5, 68, 0.18/III were 22.3 (degrees C), 56 (%), 0.22 (m/sec). Physcial condition (noise, brightness and dust) in region I were averaged 63, 295, 63/II were 67, 138, 87/III were 63 (db), 139 (lux), 26 (microgram/m3). Harmful gas (CO2 and NO2) concentration in region I were averaged 1152, 0.008/II were 913, 0.009/III were 1367 (ppm), 0.013 (ppm). CONCLUSIONS: Temperatures were appropriate but humidities were high except partial points. Air flow showed low values in average. Values of noise, dust and CO2 were relatively high. NO2 was low but brightness was variable. These mean that adequate improvement for quiet condition and air ventilation should be considered.

BACKGROUND: The cuff pressure (CP) of the laryngeal tube airway (LTA) increases during general anesthesia using nitrous oxide. However, there have been few studies on the relationship between CP and postoperative sore throat (POST). This study evaluated the efficacy of the CP on a POST on the recovery time and postoperative day. METHODS: Forty patients were divided into two groups, group M (n = 20) and group I (n = 20). In all patients, the CP was set to 65 cmH2O at the induction of anesthesia. In group M, the CP was maintained at 60-70 cmH2O during general anesthesia using N2O. However, in group I, the CP was allowed to increase. The CP was measured every 10 minutes during surgery in the two groups. The frequency and intensity (numerical rating scale of 0-100, NRS-101) of the sore throat was measured at recovery room (RR) and on postoperative day 1 (POD1). RESULTS: There was a significant increase in the CP in group I during general anesthesia and the CP was higher in group I than in group M (P < 0.05). The frequency of POST was higher in group I at RR (10% vs 70%) and POD1 (0% vs 35%) than in group M. In addition, the NRS-101 was higher in group I at RR and POD1 than in group M (P < 0.05). CONCLUSIONS: The CP of the LTA needs to be monitored and controlled during surgery in order to reduce POST.
