Objectives:To compare the insertion time, ease of device insertion, ease of gastric tube insertion, airway leakage pressure, and complications between the laryngeal mask airway (LMA) ProSeal (P-LMA) and I-gel (I-gel) groups.Methods:Eighty patients with age range 18-65 years who underwent elective surgery were included in the study. The study took place in the operation rooms of Haydarpaşa Numune Hospital, Istanbul, Turkey from November 2013 to April 2014. Patients were equally randomized into 2 groups; the I-gel group, and the P-LMA group. In both groups, the same specialist inserted the supraglottic airway devices. The insertion time of the devices, difficulty during insertion, difficulty during gastric tube insertion, coverage of airway pressure, and complications were recorded.Results:The mean insertion time in the I-gel group was significantly lower than that of the P-LMA group (I-gel: 8±3; P-LMA: 13±5 s). The insertion success rate was higher in the I-gel group (100%, first attempt) than in the P-LMA group (82.5%, first attempt). The gastric tube placement success rate was higher in the I-gel group (92.5%, first attempt) than in the P-LMA group (72.5%, first attempt). The airway leakage pressures were similar.Conclusion:Insertion was easier, insertion time was lower, and nasogastric tube insertion success was higher with the I-gel application, and is, therefore, the preferred LMA.

OBJECTIVE:Antagonism of the central nervous system inhibitor neurotransmitter gamma-Aminobutyric acid (GABA) or serotonergic system activation is an important factor in the pathogenesis of intrathecal morphine-induced pruritus. This study tested the hypothesis that preoperative use of ondansetron, gabapentin or mirtazapine can prevent morphine-induced pruritus.METHODS:We randomly allocated 80 patients of American Society of Anesthesiology (ASA) classification I and II physical status who were to undergo unilateral inguinal hernia or pilonidal sinus operations under spinal anesthesia into 4 equal groups. The first 3 groups received oral doses of 30 mg mirtazapine, 8 mg ondansetron, and 1200 mg gabapentin at 2 hours, 10 minutes, and 1 hour before surgery, respectively, and the fourth group was given a placebo. All patients received intrathecal injection of 15 mg of 0.5% hyperbaric bupivacaine and 0.2 mg morphine. Pruritus was evaluated at 0, 3, 6, 9, 12, and 24 hours after intrathecal morphine administration, and details of presence, onset time, duration, localization, and severity of pruritus were recorded.RESULTS:Incidence of pruritus was significantly more frequent in the placebo group compared to ondansetron, gabapentin, and mirtazapine groups (70%, 55%, 35%, and 35%, respectively). In general, onset of pruritus was between 2 and 6 hours after intrathecal morphine injection; however, onset in the gabapentin group (mean±SD: 4.75±2.7 hours; p=0.019) was delayed compared to other groups. It was observed that pruritus persisted relatively longer in the ondansetron and placebo groups (mean±SD: 6±3.08; 5.82±2.96 hours, respectively; p=0.047). No statistical determination was made regarding location of pruritus. Severity of pruritus was greater in the placebo group (p=0.0001). Necessity for antipruritic treatment was not statistically significantly different between groups.CONCLUSION:Incidence and severity of intrathecal morphine-induced pruritus decreased with use of each of all 3 drugs compared to placebo.

Aim:To evaluate the effects of morphine and fentanyl added to bupivacaine and intrathecal bupivacaine to combine spinal-epidural anaesthesia during caesarean.Methods:Forty subjects with American Society of Anesthesiologists I-II status who would have caesarean were included in the study. The subjects were divided into two groups. Group bupivacaine-fentanyl (BF) were given 0.5% bupivacaine 7.5 mg + 25 µg fentanyl and group bupivacaine-morphine (BM) received 0.5% bupivacaine 7.5 mg + 0.1 mg morphine intrathecal total 2 mL. Periods for access to T4 block, two dermatome regression of sensory block, time elapsed between the administration of the local anaesthetic and reaching Bromage scale 1, reaching the highest level of motor block, first analgesic necessity, umbilical cord clamping time, and when the operation ends were recorded. One-minute and five-minute Apgar scores, umbilical blood gas values of the newborns and the adverse effects were recorded. Results:Comparisons between the two groups show that group BM has longer periods for motor block start time, two dermatome regression time, and first anaesthetic necessity time and group BF had higher levels for motor block level at the 1 st minute and visual analog scale scores at postop 60 th minute. There was no significant difference between the groups for the adverse effects. Conclusion:Fentanyl and morphine added to intrathecal bupivacaine show similar effects in intraoperative analgesia. We Amaç: Sezaryenlerde kombine spinal-epidural anestezide intratekal bupivakain ve bupivakaine eklenen fentanil ve morfinin etkilerini değerlendirmektir.Yöntemler: Sezaryen operasyonu geçirecek Amerikan Anestezi Derneği I-II grubunda, 40 olgu çalışmaya alındı. Olgular iki gruba ayrıldı. Grup bupivakain-fentanile (BF) 7,5 mg %0,5 bupivakain + 25 µg fentanil, grup bupivakain-morfine (BM) 7,5 mg %0,5 bupivakain + 0,1 mg morfin intratekal olarak total 2 mL verildi. T4 duyusal bloğa ulaşma, duyusal bloğun iki dermatom gerileme, lokal anestezinin verilmesinden Bromage skalasının 1 olma süreleri, motor bloğun en üst skalaya ulaşma süresi, motor bloğun tamamen kaybolma süresi, ilk analjezik ihtiyacı süresi, bebeğin umblikal korda klemp konma süresi, operasyon bitim süresi kaydedildi. Olguların deri ve uterus insizyonu, periton kapatma, postoperatif 30 dakika, 60 dakika ve ağrı duydukları andaki ağrı şiddetleri ve ulaşılan en üst motor blok skalası kaydedildi. Yenidoğan birinci-beşinci dakika Apgar değerleri ve umblikal kan gazı değerleri ve yan etkiler kaydedildi. Bulgular:Gruplar arasında yapılan karşılaştırmalarda, grupların motor blok başlama zamanı, iki dermatom gerileme süresi, ilk analjezik ihtiyacı süresi grup BM'de uzun bulunurken, birinci dakika motor blok seviyesi ve postop 60 dakika visuel analog skalaları ise grup BF'de daha yüksek bulundu. Yan etkiler açısından gruplar arasında anlamlı farklılık bulunmadı.
