BACKGROUND: Unplanned extubation (UE) of patients requiring mechanical ventilation in an intensive care unit (ICU) is associated with poor outcomes for patients and organizations. This study was conducted to assess the clinical features of patients who experienced UE and to determine the risk factors affecting reintubation after UE in an ICU. METHODS: Among all adult patients admitted to the ICU in our institution who required mechanical ventilation between January 2011 and December 2013, those in whom UE was noted were included in the study. Data were categorized according to noninvasive or invasive management after UE. RESULTS: The rate of UE was 0.78% (the number of UEs per 100 days of mechanical ventilation). The incidence of self-extubation was 97.2%, while extubation was accidental in the remaining patients. Two cases of cardiac arrest combined with respiratory arrest after UE were noted. Of the 214 incidents, 54.7% required invasive management after UE. Long duration of mechanical ventilation (odds ratio [OR] 1.52; 95% confidence interval [CI] 1.32-1.75; p = 0.000) and high ICU mortality (OR 4.39; 95% CI 1.33-14.50; p = 0.015) showed the most significant association with invasive management after UE. In multivariate analysis, younger age (OR 0.96; 95% CI 0.93-0.99; p = 0.005), medical patients (OR 4.36; 95% CI 1.95-9.75; p = 0.000), use of sedative medication (OR 4.95; 95% CI 1.97-12.41; p = 0.001), large amount of secretion (OR 2.66; 95% CI 1.01-7.02; p = 0.049), and low PaO2/FiO2 ratio (OR 0.99; 95% CI 0.98-0.99; p = 0.000) were independent risk factors of invasive management after UE. CONCLUSIONS: To prevent unfavorable clinical outcomes, close attention and proper ventilatory support are required for patients with risk factors who require invasive management after UE.

Input signals originating from baroreceptors and vestibular receptors are integrated in the rostral ventrolateral medulla (RVLM) to maintain blood pressure during postural movement. The contribution of baroreceptors and vestibular receptors in the maintenance of blood pressure following hypotension were quantitatively analyzed by measuring phosphorylated extracellular regulated protein kinase (pERK) expression and glutamate release in the RVLM. The expression of pERK and glutamate release in the RVLM were measured in conscious rats that had undergone bilateral labyrinthectomy (BL) and/or sinoaortic denervation (SAD) following hypotension induced by a sodium nitroprusside (SNP) infusion. The expression of pERK was significantly increased in the RVLM in the control group following SNP infusion, and expression peaked 10 min after SNP infusion. The number of pERK positive neurons increased following SNP infusion in BL, SAD, and BL+SAD groups, although the increase was smaller than seen in the control group. The SAD group showed a relatively higher reduction in pERK expression when compared with the BL group. The level of glutamate release was significantly increased in the RVLM in control, BL, SAD groups following SNP infusion, and this peaked 10 min after SNP infusion. The SAD group showed a relatively higher reduction in glutamate release when compared with the BL group. These results suggest that the baroreceptors are more powerful in pERK expression and glutamate release in the RVLM following hypotension than the vestibular receptors, but the vestibular receptors still have an important role in the RVLM.

PURPOSE: This study was done to evaluate the effects of a short-term life review on spiritual well-being, depression, and anxiety in patients with terminal cancer. METHODS: The study used a pre posttest quasi experimental design with a nonequivalent control group. Measurement instruments included the Functional Assessment of Chronic Illness Therapy-Spiritual scale (FACIT-Sp12) and the Hospital Anxiety and Depression Scale (HADS). Participants were 32 patients with terminal cancer who were receiving chemotherapy or palliative care at hospitals or at home. Eighteen patients were assigned to the experimental group and 14 to the control group. A sixty minute short-term life review session was held twice a week as the intervention with the experimental group. RESULTS: There was a statistically significant increase in spiritual well-being in the experimental group compared to the control group. There were also significant decreases in depression and anxiety in the experimental group compared to the control group. CONCLUSION: The results indicate that a short-term life review can be used as a nursing intervention for enhancing the spiritual well-being of patients with terminal cancer.

BACKGROUND: Opioid-based patient controlled analgesia (PCA) provides adequate pain control following spinal surgeries at the expense of increased risk of postoperative nausea and vomiting (PONV). We evaluated the efficacy of dexamethasone added to ramosetron, which is a newly developed five-hydroxytryptamine receptor 3 antagonist with a higher receptor affinity and longer action duration compared to its congeners, on preventing PONV in highly susceptible patients receiving opioid-based IV PCA after spinal surgery. METHODS: One hundred nonsmoking female patients undergoing spinal surgery were randomly allocated to either a ramosetron group (group R) or a ramosetron plus dexamethasone group (group RD)., Normal saline (1 ml) or 5 mg of dexamethasone was injected before anesthetic induction, while at the end of the surgery, ramosetron (0.3 mg) was administered to all patients and fentanyl-based IV PCA was continued for 48 hrs. The incidence and severity of PONV, pain score and the amount of rescue antiemetics were assessed for 48 hours after surgery. RESULTS: The number of patients with moderate to severe nausea (20 vs. 10, P = 0.029), and overall incidence of vomiting (13 vs. 5, P = 0.037) were significantly lower in the group RD than in the group R, respectively. Rescue antiemetic was used less in the RD group without significance. CONCLUSIONS: Combination of ramosetron and dexamethasone significantly reduced the incidence of moderate to severe nausea and vomiting compared to ramosetron alone in highly susceptible patients receiving opioid-based IV PCA after surgery.

Liver fibrosis is a chronic liver disease and lots of people in Korea are suffered. There are many efforts to find candidates to suppress liver fibrogenesis and several chemical-induced model or bile duct ligation model have been used to research and develop hepatic fibrogenic suppressor. From the previous study about functional effects of turnip which cultivated in Kangha Island, we got the feasibility which turnip might be able to inhibit heptatic fibrogenesis. TAA is a representative hepatic fibrosis inducer, repeated 7-weeks i.p. injection of it results in hepatic fibrosis. We compared the level of hepatic fibrosis in TAA-turnip group, TAA group, and vehicle control group. Nodules-formed by TAA were observed; they were rarely shown in vehicle control group, observed in most area in TAA group, but only shown in periportal regions in TAA-turnip group. These results were confirmed through Masson's trichrom stain; fibrous structures increased in TAA group (fibrosis score: 4) but significantly decreased in TAA-turnip group (fibrosis score: 2-3). In conclusion, we got the result that turnip water extract has a potency to protect TAA-induced hepatic fibrogenesis but it is necessary further study to find its mechanism.

BACKGROUND: Opioid based patient-controlled analgesia (PCA) effectively provides adequate pain control after spine surgery, often at the expense of high incidence of postoperative nausea and vomiting (PONV). This study was designed to compare the effect of ramosetron with ondansetron for preventing PONV in highly susceptible patients using PCA following spine surgery under general anesthesia. METHODS: Seventy female patients, aged 18 to 65, scheduled for elective lumbar spine surgery, were randomly allocated into either ondansetron group (Group O, n = 35) or ramosetron group (Group R, n = 35). In patients assigned to group O, ondansetron 4 mg was injected and 12 mg was added to the PCA regimen. In patients assigned to group R, ramosetron 0.3 mg was injected and 0.3mg was added to the PCA regimen. The PCA regimen consisted of fentanyl 25microgram/kg (total volume including saline: 100 ml) and was programmed to deliver 2 ml/hr as background infusion and 0.5 ml per demand with a 15 min lockout. The incidence and severity of PONV, pain score, total amount of administered rescue analgesic and rescue antiemetic were assessed following 48 hrs after surgery. RESULTS: The incidence of PONV showed no significant differences between groups during 48 hrs after surgery. There were no differences in the severity of nausea, pain score, total amount of administered rescue analgesic and rescue antiemetic between groups. CONCLUSIONS: Ramosetron prophylaxis for preventing PONV is as effective as ondansetron in highly susceptible patients using fentanyl based PCA following spine surgery under general anesthesia.

PURPOSE: We wanted to evaluate the clinical efficacy of an increased computed tomography attenuation coefficient (CTAC) of urine after the oral administration of iohexol in neonates who are suspected of suffering with neonatal necrotizing enterocolitis (NEC). MATERIALS AND METHODS: During a recent 1 year-period, seventeen neonates were admitted for suspected NEC, and they were divided into the suspected and definite groups based on their clinical signs and radiographic findings; we also included ten normal neonates as the control group. Diluted iohexol was administered and the CTACs of collected urine samples at 8-12 hour intervals were measured. Comparative analysis of the three groups was done and statistical significance was determined by the Scheffe test. RESULTS: Among 17 neonates, there were 13 neonates in the suspect group and 4 neonates in the definite group. The mean CTACs of urine in each group were 2711 HU (control group), 3411 HU (suspected group), and 7625 HU (definite group), respectively. There was a significant difference between the mean CTAC of the definite group and that of the control or suspected groups (Scheffe t >2.65). However, no statistically significant difference was seen between the suspected and control groups (Scheffe t=1.14). CONCLUSION: Although measurements of the CTAC of urine showed no significant diagnostic efficacy in the suspected group, the CTAC of urine, which reflects the correlated degree of bowel mucosal injury, can be a useful aid for determining the severity and progression of NEC.
