Radiofrequency versus injection snoreplasty in simple snoring.

OBJECTIVE: To compare the efficacy and tolerance of controlled temperature radiofrequency (RF) and injection snoreplasty (IS) for the treatment of simple snoring. STUDY DESIGN: The study was a nonrandomized, prospective study conducted on 70 simple snorers. Efficacy of the operations was subjectively evaluated by the bed partners and after 6 weeks of the last treatment. Tolerance was evaluated by the patient during first 10 postoperative days. Postoperative pain and discomfort level were assessed. RESULTS: Satisfaction in terms of snoring severity was reported by 87.5% of the cases with RF and by 76.7% of the patients with IS. Discomfort levels also were similar for both groups CONCLUSIONS: Controlled-temperature RF and IS were both effective on snoring and well tolerated by the patients. This allows retreatments if necessary.

[Comparison of ropivacaine, ropivacaine plus tramadol and ropivacaine plus morphine in patients undergoing minor hand surgery]. / Minör el cerrahisinde rejyonal intravenöz anestezide ropivakain, ropivakain-tramadol ve ropivakain-morfinin karsilastirilmasi.

In our study we aimed to compare the effects of ropivacaine alone, ropivacaine plus tramadol HCl, and ropivacaine plus morphine HCl used as intravenous regional anesthesia (IVRA), on duration to the initiation of analgesia, total analgesia time, analgesic requirement, sedation levels and hemodynamic parameters. 53 patients undergoing minor hand surgery were included into the study. Patients were randomly divided into three groups to receive 40 ml of ropivacaine 0.2 % (Group R, n=18), ropivacaine 0.2 % plus 1 mg/kg tramadol HCl (Group RT, n=18), and ropivacaine 0.2 % plus 0.1 mg/kg morphine HCl (Group RM, n=17) as IVRA. Following the injection, the durations for the initiation of analgesia were recorded. Levels of sedation, analgesia (VAS) and hemodynamic parameters were recorded in 5 minute intervals throughout first 35 minutes intraoperatively and at 1, 5, 10, 15, 20, 30, 45 and 60th minutes postoperatively. Patients were asked about the initiation of pain and requirements of analgesic at the first postoperative day. The duration to the initiation of analgesia was similar between the groups. Total analgesia time was found to be 304.0 +/- 317.6 min in Group R, 327.0 +/- 316.5 min in Group RT, and 635.9 +/- 492.3 min in Group RM. The difference between Group R and RM was statistically significant (p<0.05). Analgesic requirements were similar between the groups (p>0.05). Mild local anesthetic toxicity was observed in Group RM in two patients. We conclude that, when used as IVRA, ropivacaine alone or with tramadol or morphine produced similar analgesia and surgery conditions, and ropivacaine plus morphine had more adverse effects besides its longer duration of analgesia.

Patient-controlled intravenous analgesia with remifentanil in nulliparous subjects in labor.

OBJECTIVE: in this study we controlled the efficiency and safety of using remifentanil combined with two different supplementary background infusions for labor analgesia in nulliparous patients. RESEARCH DESIGN AND METHODS: 60 subjects were allocated to two groups. After programming the patient-controlled analgesia device to deliver a fixed load and demand doses of intravenous remifentanil for all subjects, group r (n = 30) received a background infusion of remifentanil 0.1 microg/kg/min and group R (n = 30) received a supplementary infusion of remifentanil 0.15 microg/kg/min. Visual analogue scale for analgesia, hemodynamic parameters, sedation scales and fetal heart rates were recorded at the 5th, 10th, 20th and 30th min of the study and measurements continued every 15 min during 90 min of labor and delivery. Side effects, Apgar and satisfaction scores were obtained for every subject. RESULTS: visual analogue scale scores of group R were significantly lower than those of group r throughout labor and delivery (p < 0.05). Hemodynamic parameters and fetal heart rates of the two groups were not different (p > 0.05). Most subjects were awake and only nausea was obtained (p > 0.05). The increase in the Apgar and satisfaction scores was not statistically significant (p > 0.05). CONCLUSION: it was determined that remifentanil with a 15-mug demand dose and 0.15 mug/kg/min supplementary continuous infusion is an effective choice for patient-controlled analgesia during labor in nulliparous subjects.

A background infusion of morphine enhances patient-controlled analgesia after cardiac surgery.

PURPOSE: We compared the efficacy of patient-controlled analgesia (PCA), with or without a background infusion of morphine, on postoperative pain relief in patients extubated in the operating room after coronary artery bypass grafting (CABG) surgery. METHODS: With Faculty Ethics approval, 60 consenting adults undergoing elective coronary artery surgery were randomly assigned to receive either morphine PCA alone (group PCA-A, n = 30) or morphine PCA plus a background infusion (group PCA-B, n = 30) for 24 hr postoperatively. Pain scores with verbal rating scale (VRS; from 0 to 10) at rest, sedation scores, morphine consumption and delivery/demand ratios were assessed at zero, one, two, four, six, 12 and 24 hr after surgery. Hemodynamic variables and arterial blood gases were also recorded in the same periods. RESULTS: Sedation scores in the two groups were similar. At all study periods after the first postoperative hour, VRS remained below 5 in both groups. Pain scores were significantly lower in the background infusion group, which also had greater cumulative morphine consumption (61.7 +/- 10.9 mg vs 38.5 +/- 16.2 mg). There were no episodes of hypoxemia or hypertension. CONCLUSION: Morphine PCA effectively controlled postoperative pain after cardiac surgery. The addition of a background infusion of morphine enhanced analgesia and increased morphine consumption.

Patient-controlled epidural analgesia after major urologic surgeries. A comparison of tramadol with or without bupivacaine.

The efficiency and safety of patient-controlled epidural analgesia by using tramadol alone and combined with bupivacaine were investigated for postoperative pain treatment after major urological surgeries. For PCEA: in group I (n = 17) a loading dose of 20 mg tramadol with a continuous infusion of 1 mg/ml tramadol at a rate of 8 ml/h was given. In group II (n = 17), patients received an initial loading dose of 20 ml bupivacaine 0.125% and a supplemental continuous infusion of 8 ml/h. In group III (n = 17), a loading dose of 20 mg tramadol with 20 ml bupivacaine 0.125% were given and a supplemental infusion of 1 mg/ml tramadol in 20 ml bupivacaine 0.125% combination was begun with a rate of 8 ml/h. A demand epidural bolus dose of 5 ml with a lockout time of 30 min was also used in all patients. VAS for pain intensity, vital signs, sedation scale and side effects was monitored at 0, 15, 30 min and 1, 2, 3, 4, 8, 12, and 24 h of the postoperative period. Statistical significance was determined using Kruskal-Wallis, Fisher's exact, analysis of variance for repeated measurements and Tukey tests. The hemodynamic values and sedation scales were insignificantly different (p > 0.05). The adequate analgesia was provided in all patients. However VAS values were significantly lower in group III than in groups I and II at every measurement (p < 0.05). The incidence of side effects in all three groups was low (p > 0.05). In conclusion, we suggested that a combination of tramadol with bupivacaine can provide the most effective and safe postoperative analgesia with minimal risk for side effects.
