PURPOSE: This study was a systematic review and meta-analysis designed to investigate the effects of stimulation-oriented interventions for behavioral problems among people with dementia. METHODS: Based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA), a literature search was conducted using seven electronic databases, gray literature, and other sources. Methodological quality was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) for randomized controlled trials (RCTs). Data were analyzed using R with the 'meta' package and the Comprehensive Meta-Analysis (CMA 2.0) program. RESULTS: Sixteen studies were included for meta-analysis to investigate the effect of stimulation-oriented interventions. The quality of individual studies was rated as '++' for eight studies and '+' for the rest. The effect sizes were analyzed according to three subgroups of interventions (light, music, and others); Hedges' g=0.04 (95% CI: -0.38~0.46), -0.23 (95% CI: -0.56~0.10), -0.34 (95% CI: -0.34~0.00), respectively. To explore the possible causes of heterogeneity (I²=62.8%), meta-regression was conducted with covariates of sample size, number of sessions, and length of session (time). No moderating effects were found for sample size or number of sessions, but session time showed a significant effect (Z=1.96, 95% CI: 0.00~0.01). Finally, a funnel plot along with Egger's regression test was performed to check for publication bias, but no significant bias was detected. CONCLUSION: Based on these findings, stimulation-oriented interventions seem to have a small effect for behavioral problems among people with dementia. Further research is needed to identify optimum time of the interventions for behavioral problems among dementia pateints.

Prolonged oversedation occurs frequently in postoperative care units, and sometimes delays transfer to normal units. Flumazenil is a known reversal drug for benzodiazepines, and is used to reverse the oversedation caused by benzodiazepines. However, we found that flumazenil was effective in a case of sevoflurane induced oversedation. A prolonged oversedation of 90 minutes occurred after sevoflurane anesthesia without benzodiazepine at a postoperative care unit. Immediately after an intravenous injection of flumazenil, the patient fully awoke and was oriented.

BACKGROUND: This study was designed to determine the effectiveness of the continuous infusion of ondansetron for the prevention of postoperative nausea and vomiting (PONV) in intravenous patient-controlled analgesia (PCA). METHODS: One hundred and sixty patients undergoing spinal surgery were randomized into four groups according to the method of ondansetron administration, placebo (n = 40, group 1), ondansetron 8 mg mixed to IV PCA (n = 40, group 2), ondansetron 4 mg IV before induction or after surgery in addition to 8 mg mixed to IV PCA (n = 40, group 3 or n = 40, group 4). The incidences of nausea, vomiting, and side effects were recorded for 48 hr postoperatively. RESULTS: The incidence of nausea in group 1 (43 %) was significantly higher than in the other groups (group 2; 18%, group 3; 15%, group 4; 18%) (P < 0.05), and vomiting was one in group 1. CONCLUSIONS: Continuous ondansetron infusion is effective at preventing PONV, but the effects of additional bolus injections to continuous infusion of ondansetron were not different from continuous infusion only.

BACKGROUND: The aim of this study was to examine the safety and efficacy of sedation and analgesia using remifentanil during percutaneous endoscopic lumbar discectomy (PELD). METHODS: Eighty ASA patients with physical status 1 or 2 who underwent a PELD were enrolled in this study. They were randomized to receive one of two treatments: a fentanyl bolus of 0.7microgram/kg 5 min before the procedure and of 0.7microgram/kg during the procedure (n = 40, group F), or a remifentanil titration at an infusion rate of 0.1-0.3microgram/kg/min available throughout the procedure according to the appeal of pain, level of sedation and side-effects (n = 40, group R). The observer's assessment of alertness/sedation (OAA/S) scale, blood pressure, heart rate, respiratory rate, SpO2, and end tidal CO2 were assessed and measured during and/or after the procedures. The visual analogue scale of pain (VAS), and the patient and endoscopist satisfaction scale were assessed after the procedures. RESULTS: There were no significant differences between the two groups in terms of the recovery characteristics, incidence of complications and satisfaction score of patients. In 92.5% of the cases among the remifentanil group, the spine surgeon made uniform judgements that remifentanil worked better than the usually used fentanyl procedure, whereas in 7.5% of the cases the effects were indifferent. The VAS score of the R group was significantly lower than that of the F group. CONCLUSIONS: We concluded that sedation and analgesia with remifentanil is very useful for painful local procedures such as PELDs.

Despite recent successful efforts to shorten the door-to-balloon time in patients with acute ST-segment elevation myocardial infarction (STEMI), prehospital delay remains unaffected. Nonetheless, the factors associated with prehospital delay have not been clearly identified in Korea. We retrospectively evaluated 423 patients with STEMI. The mean symptom onset-to-door time was 255 +/- 285 (median: 150) min. The patients were analyzed in two groups according to symptom onset-to-door time (short delay group: < or = 180 min vs long delay group: > 180 min). Inhospital mortality was significantly higher in long delay group (6.9% vs 2.8%; P = 0.048). Among sociodemographic and clinical variables, diabetes, low educational level, triage via other hospital, use of private transport and night time onset were more prevalent in long delay group (21% vs 30%; P = 0.038, 47% vs 59%; P = 0.013, 72% vs 82%; P = 0.027, 25% vs 41%; P < 0.001 and 33% vs 48%; P = 0.002, respectively). In multivariate analysis, low educational level (1.66 [1.08-2.56]; P = 0.021), symptom onset during night time (1.97 [1.27-3.04]; P = 0.002), triage via other hospital (1.83 [1.58-5.10]; P = 0.001) and private transport were significantly associated with prehospital delay (3.02 [1.81-5.06]; P < 0.001). In conclusion, prehospital delay is more frequent in patients with low educational level, symptom onset during night time, triage via other hospitals, and private transport, and is associated with higher inhospital mortality.
