Background The laryngeal mask airway (LMA) is a large foreign body that exerts pressure on the pharyngeal mucosa, which may lead to throat discomfort. To determine whether intracuff pressures are associated with such discomfort, a randomized, double-blind study was performed to determine the effect of high versus low intracuff pressures. Methods Seventy healthy women were randomly allocated to two groups with different LMA intracuff pressures: 30 mmHg (low pressure) or 180 mmHg (high pressure). Pressures were controlled with a microprocessor-controlled monitor. Insertion of the LMA was performed by one investigator and facilitated with propofol and verified fiberoptically. Anesthesia was maintained with enflurane and nitrous oxide. The LMAs were removed while the patients were still asleep. Patients assessed their laryngopharyngeal complaints (sore throat, dysphagia, hoarseness) at 8, 24, and 48 h after operation on a 101-point numerical rating scale. Results No significant difference was found in the overall incidence of complaints between both groups (low pressure: 50%; high pressure: 42%). On the day of surgery, dysphagia (38%) was more frequent than sore throat (16%) or hoarseness (6%) (P < 0.05) within the high-pressure group. In the low-pressure group, the incidence of these complaints was not significantly different (33%, 20%, and 23%, respectively). On the following day, dysphagia was still present in 20% of the women in both groups, and other symptoms comprised 10% or less of the reported complaints. Conclusions Differences in LMA intracuff pressures did not influence either the incidence or severity of laryngopharyngeal complaints.

Background: In case of general anesthesia, airway maintenance along with least complications is the most important goal of team of anesthesiologists. In case of clinical practice, the laryngeal mask airway (LMA) devices have superiority in managing supraglottic airway. Recently i-gel airway has been introduced as supraglottic airway equipment (disposable). Aim: To make comparison between laryngeal mask and I-gel with respect to postoperative complication of sore throat in case of patients who were given general anesthesia. Study design: Randomized trial Setting: Anesthesia Department Study duration: 6 after synopsis approval in total 6months of duration Methods: Candidates were divided randomly divided into two groups. In case of members of group A, patients were given i-gel where as members of group B, disposable LMA was given. General anesthesia was administered according to the standardized protocols. A day after operation, candidates were check post operatively for 24 hours, for sore throat and information was documented on Performa. Results: The candidates mean age was 44.23±15.11years in case of i-gel group members whereas 46.10±15.56 years in case of LMA group. In case of i-gel group, there were about twenty five males members and thirty five were females members . In case of LMA group members, there were about twenty six males and thirty four female members . In present case research, sore throat postoperatively was seen in case of 17(14.2%) cases, i.e. 4 (6.7%) in i-gel group while 13(21.7%) in case of LMA group. The significant difference was witnessed between members of both groups (p<0.05). Conclusion: Thus i-gel is better than LMA for general anesthesia as it has fewer chances of side effects like postoperative sore throat.

Abstract Objectives Existing treatments for fibromyalgia have limited efficacy, and only a minority of individuals clinically respond to any single intervention. This study was a prospective, multicenter, randomized, double-blind, controlled clinical trial to evaluate the feasibility of alternating magnetic field therapy in fibromyalgia patients by comparing the Angel Touch device (AT-02) with a sham control (S-01). Methods Two sites enrolled 44 subjects with diagnosed fibromyalgia. After informed consent, subjects taking prohibited concomitant drugs underwent a washout period of two or more weeks. All subjects then began a one-week run-in period. Numerical rating scale (NRS) pain scores were collected without device intervention for one day, followed by S-01 application to four or more painful sites for 10 minutes at each site, twice daily for six days. Subjects were then randomized to AT-02 or S-01, applied to four or more painful sites for 10 minutes at each site, twice daily for eight weeks. NRS scores were obtained twice daily during the entire treatment period. Results The primary end point (change in NRS ± SD at week 8 vs baseline) was –0.94 ± 1.33 in the AT-02 group and –0.22 ± 1.38 in the S-01 group. A trend toward a between-group difference in eight-week NRS scores favored the AT-02 group (–0.73, 95% confidence interval = –1.56 to 0.11, P = 0.086). An adjusted repeated measure analysis detected a significant difference in NRS scores (P = 0.039). Conclusions The reduction in NRS scores for AT-02 relative to sham was comparable to reductions observed in meta-analyses of fibromyalgia drug therapy. The unadjusted results and the persistence of the pain score reductions remain encouraging.

Introduction: Supraglottic devices are a useful advent in airway management filling a gap between the facemask and tracheal tube in terms of both anatomical position and degree of invasiveness. Laryngeal mask airway classic (LMA-C)  being first of its kind and I-gel is second generation non-inflatable supraglottic device. The objective of our study was to compare the two supraglottic devices, Laryngeal mask airway classic (LMA-C) and I-gel for a success rate of insertion and postoperative sore throat.  Materials and Methods: A total of 80 patients scheduled for elective surgical procedures were studied in a prospective, randomly assigned, comparative and interventional manner. Patients were randomly allocated into two groups with forty patients in each group. I-gel and LMA-C were used in Groups 1 and 2 respectively. After achieving adequate depth of anesthesia the supraglottic device of appropriate size was inserted. The success rate of insertion of the device was represented by the number of insertion attempts. In the postoperative ward within 24 hours after surgery patient was asked whether a sore throat was present.  Results: There was a statistically significant difference between the two supraglottic devices in terms of successful attempts of insertion (p-value 0.02).In group 1(I-gel)34 out of 40 patients had first attempt insertion success,6 patients in the second attempt, and no patient had third insertion attempt. In group 2 (LMA-C) first-time insertion success was in 14 patients, 23 patients in the second attempt, and 3 patients in the third attempt. The incidence of postoperative sore throat was higher in the LMA-C group than the I-gel group(17.5% vs 5% respectively) with a p-value of 0.154.  Conclusion: Compared to the laryngeal mask airway classic, I-gel was inserted with less number of attempts and had a lower incidence of postoperative sore throat.

Abstract Background There are doubts among anesthesiologists on the use of the Laryngeal Mask Airway (LMA) in nasal surgeries because of concerns about the occurrence of blood leakages to the airway. We hypothesized that the use of LMA-Supreme (LMA-S) in nasal surgery is comparable with endotracheal tube (ETT) according to airway protection against blood leakage through the fiberoptic bronchoscopy, oropharyngeal leakage pressure (OLP), heart rate (HR), mean arterial pressure (MAP), and postoperative adverse events. Methods The present study was conducted in a prospective, randomized, single-blind, controlled manner on 80 patients, who underwent septoplasty procedures under general anesthesia, after dividing them randomly into two groups according to the device used (LMA-S or ETT). The presence of blood in the airway (glottis/trachea, distal trachea) was analyzed with the fiberoptic bronchoscope and a four-point scale. Both groups were evaluated for OLP; HR; MAP; postoperative sore throat, nausea, and vomiting; dysphagia; and dysphonia. Results In the fiberoptic evaluation of the airway postoperatively, less blood leakage was detected in both anatomic areas in the LMA-S group than in the ETT group (glottis/trachea, p = 0.004; distal trachea, p = 0.034). Sore throat was detected less frequently in the LMA-S group at a significant level in the 2nd, 6th, and 12th hours of postoperative period; however, other adverse events were similar in both groups. Hemodynamic parameters were not different between the two groups. Conclusion The present findings demonstrate that the LMA-S provided more effective airway protection than the ETT in preventing blood leakage in the septoplasty procedures. We believe that the LMA-S can be used safely and as an alternative to the ETT in septoplasty cases.

Introduction. In this study we are aiming to evaluate the changes of serum serotonin and its association with pain in patients suffering from chronic low back pain before and after lumbar discectomy surgery. Patients and Methods. A prospective study was performed on the patients referring to the outpatient clinic in Besat hospital, Hamadan University of Medical Sciences, Hamadan, Iran, during 2016. A 2 mL fasting blood sample was collected from each patient at preoperative day 1 and postoperative day 14 and they were measured for level of serum serotonin. Besides, all patients were asked for severity of their low back pain in preoperative day 1 and postoperative day 14 and scored their pain from zero to ten using a Numerical Rating Scale. Results. Forty patients with the mean age of 47 ± 13 yrs/old (range 25–77) including 15 (37.5%) males were enrolled into the study. The overall mean score of preoperative pain was significantly decreased from 7.4 ± 2.18 (range 4–10) to the postoperative pain score 3.87 ± 2.92 (range 0–10) (P < .001). The overall levels of pre- and postoperative serum serotonin were 3.37 ± 1.27 (range 1.1–6.4) and 3.58 ± 1.32 (range .94–7.1) ng/mL, respectively, with no significant difference (P = .09). The levels of pre- and postoperative serum serotonin were significantly higher in males and patients older than 50 yrs/old compared to the females and patients younger than 50 yrs/old, respectively (P = .03 and .005, respectively). A significant inverse correlation between the postoperative levels of pain and serum serotonin was observed (r = -.36 and P = .02). Conclusion. A negative medium strength linear relationship may exist between the postoperative serum serotonin and low back pain.

Background Optimal surgical treatment of lateral epicondylitis remains uncertain. Recently, radiofrequency microtenotomy (RFMT) has been proposed as a suitable treatment. We compared RFMT with standard open release (OR) in this prospective randomized controlled trial. Methods In total, 41 patients with symptoms for at least 6 months were randomized into two groups: 23 patients had RFMT and 18 had OR. Two patients from RFMT withdrew. Each patient underwent Numerical Rating Scale (NRS) pain score, grip strength and Disabilities of the Arm, Shoulder and Hand (DASH) scores pre-operatively and at 6 weeks. Pain and DASH scores were repeated at 6 months and 12 months. Results NRS pain scores improved by 4.8 points for RFMT and by 3.9 points for OR. There was a significant improvement in both groups from pre-operative scores, although there was no statistically significant difference between the groups at 1 year. Grip strength improved by 31% in the RFMT group compared to 38% in OR. There was no significant difference between the initial and 6 weeks scores or between treatments. At 1 year, DASH was 39.8 points for RFMT and 24.4 points for OR. There was a significant improvement in both groups from pre-operative scores, although there was no statistically significant difference between the groups at 1 year. Conclusions Both groups showed significant improvements and similar benefit to the patient. The results of the present study do not show any benefit of RFMT over the standard OR. As a result of the extra expense of RFMT, we therefore recommend that OR is offered as the standard surgical management.

Background: Laparoscopic cholecystectomy is established as gold standard for management of cholelithiasis. Intraoperative pneumoperitoneum affects the postoperative outcomes. The current stress is on increasing patient safety. Hence, this prospective study was undertaken to compare the effect of low pressure pneumoperitoneum (LPP <10 mm Hg) versus high pressure pneumoperitoneum (HPP > 14 mm Hg) on postoperative pain and ileus.Methods: 120 patients undergoing laparoscopic cholecystectomy were randomized into the LPP (<10mm Hg) group (n=60) and the HPP (>14 mm Hg) group (n=60). Total duration of surgery, intra-operative gas consumption, occurrence of bile spillage during operation, shoulder pain and abdominal pain in postoperative period, additional requirement of analgesia in postoperative period and postoperative ileus were assessed.Results: There was no significant difference in terms of operative duration, consumption of CO2 gas, intraoperative bile spillage, total hospital stay and tolerance to early feeding. The incidence of shoulder pain was higher in patients who underwent HPP laparoscopic cholecystectomy (p<0.05). There was early recovery and early return of bowel activity in LPP which was statistically significant.Conclusions: Low-pressure pneumoperitoneum is feasible and safe and results in reduced postoperative shoulder tip pain and near-equal operative time with early return of bowel activity compared with high-pressure pneumoperitoneum.
