Background: The aim of our study was to evaluate the antiemetic effects of intravenous dexamethasone in preventing continuously infused epidural morphine-related nausea and vomiting. Methods: Twenty-seven patients requiring general anesthesia for gastrectomy were enrolled in a randomized, double-blinded, and placebo-controlled study. At the end of surgery, all patients received epidural morphine 3 mg and were connected to an epidural morphine infusion pump for 2 days in order to relieve postoperative pain. Before the morphine injection, the dexamethasone group (n = 12) received IV dexamethasone 10 mg, whereas the saline group (n = 15) received IV saline. The incidence of nausea & vomiting, pruritus, back pain and VAS scores were assessed in the recovery room, and at 24 h and 48 h postoperatively. Results: There was no significant difference in the total incidence of nausea and vomiting, pruritus, back pain or in the VAS scores. However, there was no vomiting and no back pain in the dexamethasone group. Conclusions: Intravenous dexamethasone did not significantly decrease the total incidence of nausea or vomiting in patients receiving continuous epidural morphine for postoperative pain control. However, IV dexamethasone appears to decrease the severity of nausea, vomiting and back pain.

Purpose: A eutectic mixture of local anesthetics (EMLA$^{(R)}$) cream has been used as a topical anesthetic to reduce the pain of procedures penetrating the skin. It is generally applied for 40 to 60 minutes before the painful procedure. Because of the long application period, EMLA$^{(R)}$ is not useful in the emergency department (ED). The purpose of this study was to determine whether a 20-minute application of 9.6% lidocaine would be useful in reducing the pain of routine peripheral intravenous cannulation in the ED. Methods: We examined 27 male and 19 female patients ages over 18 years of age who required intravenous cannula insertion. Intravenous insertion was performed on 46 patients: 24 patients in the placebo group (mean age: 40.0 years) and 22 in the 9.6% lidocaine group (mean age: 37.6 years). The 9.6% lidocaine or placebo gel was applied and covered with an occlusive dressing for 20 minutes. Pain was scored by the patients using a 0- to 10-cm visual analogue scale. Results: The patients in the 9.6% lidocaine group (mean pain score: 3.4) experienced less pain than those in the placebo group (mean: 5.3), and the difference was statistically significant (p=0.029). Conclusion: We concluded that a 20-minute application of 9.6% lidocaine is safe and effective for reducing pain associated with venipuncture.

To compare the sedative effects using intermittent intravenous bolus injection with tiletamine-zolazepam (n = 5, TZ group), xylazine-ketamine (n = 5, XK group) and propofol (n = 5, PI group), we investigated the changes of hemodynamic (heart rate, arterial pressure), $SpO_2$, rectal temperature, respiratory rate and pain score during 60 minute sedation and 40 minute recovery period in beagle dogs. The value of rectal temperature was significantly higher in PI groups (p<0.05) during recovery period. The value of heart rate was significantly lower in XK group (p<0.05) during sedation. The changes of respiratory rate were similar tendency in all groups. The change of $SpO_2$ was stable during sedation and value was significantly higher in PI group (p<0.05) during recovery period. The value of systolic arterial pressure (SAP) was significantly lower in XK group (p<0.05) than PI group during sedation and recovery period. Low analgesic effect occurred in PI group. We concluded that intravenous anesthesia by intermittent bolus injection with propofol is useful in stabilizing rectal temperature, $SpO_2$ and hemodynamic during sedation and provide fast recovery, but have low analgesic effect.

Dental treatment of mentally challenged patients under general anesthesia is a series of challenging procedures not only for dental operators but also for dental anesthesiologists. Patients presenting with uncooperative behavior often resist the perioperative management for adesthestic administration. This case report suggests oral premedication as a conjuctive method for anestheitic induction. A 26-year-old male dental patient with autism was referred to dental treatment under general anesthesia. The patient refused to enter dental clinic office and was not able to receive preoperative assessment. In the day of operation, 15 mg of midazolam was given to the patient for oral premedication prior to anesthetic induction. Ater 20 minutes, the patient presented with drowziness and was transferred to the office. Anesthestic staff were able to achieve appropriate intravenous access and mask inhalation. The patient recieved 8 hrs long dental treatment and recovered in a noncomplicated way. Oral midazolam is commonly used to reduce anxiety for combative and irritated pateints. In this case, oral midazolam sedation was used as a preanesthetic management of a highly uncoopearive patient.

Attention deficit hyperactivity disorder (ADHD) is characterized by inattention, impulsivity, and hyperactivity. Given high incidence of ADHD, many children with ADHD is likely to present for anesthesia. This case report suggests intramuscular premedication as an alternative method for anesthetic induction. A 9-year-old male patient with ADHD was transferred for dental treatment under general anesthesia. The patient refused to go into dental clinic office. Oral midazolam was given to the patient, however, he was resistant to take midazolam via oral route. Instead, we administer midazolam and ketamine via intramuscular route. After less than 10 miniutes, the patient became drowsy and was transferred to dental chair. Intravenous access and mask inhalation was possible. The patient received dental treatment under general anesthesia and recovered in a non-complicated way. In this case, intramuscular sedation with midazolam and ketamine was used as a premedication in highly uncoopearive patient refused to take oral sedative medication.

Dexmedetomidine is an ${\alpha}2$-adrenergic receptor agonist that exhibits a protective effect on ischemia-reperfusion injury of the heart, kidney, and other organs. In the present study, we examined the neuroprotective action and potential mechanisms of dexmedetomidine against ischemia-reperfusion induced cerebral injury. Transient focal cerebral ischemia-reperfusion injury was induced in Sprague-Dawley rats by middle cerebral artery occlusion. After the ischemic insult, animals then received intravenous dexmedetomidine of $1{\mu}g/kg$ load dose, followed by $0.05{\mu}g/kg/min$ infusion for 2 h. After 24 h of reperfusion, neurological function, brain edema, and the morphology of the hippocampal CA1 region were evaluated. The levels and mRNA expressions of interleukin-$1{\beta}$, interleukin-6 and tumor nevrosis factor-${\alpha}$ as well as the protein expression of inducible nitric oxide synthase, cyclooxygenase-2, nuclear factor-${\kappa}Bp65$, inhibitor of ${\kappa}B{\alpha}$ and phosphorylated of ${\kappa}B{\alpha}$ in hippocampus were assessed. We found that dexmedetomidine reduced focal cerebral ischemia-reperfusion injury in rats by inhibiting the expression and release of inflammatory cytokines and mediators. Inhibition of the nuclear factor-${\kappa}B$ pathway may be a mechanism underlying the neuroprotective action of dexmedetomidine against focal cerebral I/R injury.

Background: There are cases in which shoulder pain persists long after shoulder joint surgery and this pain can not be reduced by intravenous patient controlled analgesia (IVPCA). Our purpose was to evaluate the effect of stellate ganglion block (SGB) on postoperative shoulder pain and also to investigate the effect of preventive SBG on complex regional pain syndrome (CRPS). Methods: Forty patients, who were evaluated to ASA class 1 and 2 and who were scheduled for shoulder joint surgery under general anesthesia, were randomly divided into 2 groups. The experimental group of patients (n = 20) received SGB with 0.5% mepivacaine 8 ml after induction of general anesthesia. The control group of patients (n = 20) received only general anesthesia. Their postoperative pain was assessed using the visual analog scale (VAS) at 30 min, 1, 2, 6, 12, 24 and 48 hours postoperatively. Whenever patients wanted supplemental analgesia, diclofenac sodium 75 mg was injected intramuscularly and the need for supplemental analgesia was recorded. Results: The experimental group of patients had significantly lower pain scores at 30 min, 1, 2 and 6 hours and also significantly lower analgesic requirement at 1, 2 and 6 hours. Conclusions: We found SGB was effective for controlling postoperative pain after shoulder joint surgery. Also, we could expect that SGB reduced the incidence of CRPS.

Background: Propofol has been used extensively for short-acting intravenous sedative agent during monitored anesthesia care (MAC). This study was designed to evaluate the safety and availability of MAC using propofol in implant surgery of the one-day admission patients. Methods: In this study, subjects were divided into two groups according to ASA physical status. The heart rate, blood pressure, peripheral oxygen saturation and ECG of a patient were estimated under MAC by an anesthesiologist and the vital signs were recorded in recovery room periodically afterwards. The subjective satisfaction with regard to outpatient ambulatory surgery under MAC procedure was evaluated the next day. Results: Systolic and diastolic blood pressure were significantly decreased during MAC in ASA I group, but other remarkable changes in vital sign were not observed. There was no significant difference in pain and anxiety level between ASA I and ASA II, III group. Satisfaction rate was high in both groups. Conclusion: Monitored-Anesthesia Care using propofol during implant surgery of the one-day admission patients might be safe and available procedure because heart rate, blood pressure and oxygen saturation are stable before and during surgery, and adequate control of pain and anxiety is supported.

Purpose: This study aimed to assess combined effects of early oral feeding after Cesarean section (C/S) under regional anesthesia on bowel function, gastrointestinal complications and surgical recovery. Methods: A systematic literature search was conducted using KISS, RISS, PubMed, CINAHL, EMBASE, CENTRAL and Google Scholar to identify randomized clinical trials comparing early oral feeding (EOF) with delayed oral feeding (DOF) after C/S. Outcome variables were bowel function and gastrointestinal complications and surgical recovery. Effect size was calculated using weighted mean differences (WMDs) and relative risks (RRs), with 95% confidence intervals (CIs). Results: Seven studies involving 1,911 patients from 568 studies, 7 studies were included in meta-analysis. EOF was significantly associated with shorter time to recover bowel movement compared with DOF (WMD, - 2.50; CI, - 3.50~- 1.50). EOF was not associated with nausea (RR, 1.15; CI, 0.87~1.53) and vomiting (RR, 0.96; CI, 0.65~1.42), but lower incidence of abdominal distension (RR, 0.70; CI, 0.50~0.98). EOF was significantly associated with shorter time to discontinuation of intravenous fluids (WMD, - 8.88; 95% CI, - 16.65~- 1.11) and removal of urinary catheter (WMD, - 15.23; CI, - 25.62~- 4.85). Conclusion: This meta-analysis provides evidence that EOF after C/S under regional anesthesia not only accelerates return of bowel function and surgical recovery but also reduces gastrointestinal complications. These results suggest that EOF should be offered to women who have undergone C/S to improve the recovery experience and reduce overall medical costs.
