Background and Objectives : Supraglottic airway devices (SADs) are known to be useful in eliminating the drawbacks of laryngoscopy and tracheal intubation, especially ocular pressure and stress responses. The ultrasonographic measurement of optic nerve sheath diameter (ONSD) reflects increases in intracranial pressure (ICP). In our study, we aimed to compare the effects of SADs on hemodynamic response and ONSD. Materials and Methods : Our prospective study included 90 ASA I-II patients over the age of 18 who did not have a history of difficult intubation or ophthalmic pathology...

BACKGROUND AND AIMS: Oropharyngeal leak pressure (OLP) of LMA Protector is reported to be higher compared to other second generation supraglottic devices (SGDs) indicating better seal with patient's airway and hence enhanced safety. To ascertain its benefit in patients undergoing surgeries where head and neck position other than neutral is required, we conducted a prospective randomized study to compare OLP of LMA Protector with LMA-ProSeal (PLMA) with head and neck in neutral, extension, flexion, and rotation position...

METHODS: This prospective observational study included 100 adult patients of American Society of Anesthesiologists (ASA) Grade I and II, undergoing elective surgery under General Anesthesia requiring Proseal LMA™ placement as an airway device. LMA placement was first confirmed by clinical tests...

BACKGROUND: Surgeon and anesthetist share the airway in a simpler way in the resection and reconstruction phase of tracheal surgery in tubeless spontaneous-ventilation video-assisted thoracoscopic surgery (SV-VATS). Tubeless SV-VATS means stable spontaneous ventilation in the resection and reconstruction phase to anesthesiologist, and unobstructed surgical field to surgeon. What's the ideal airway management strategy during "Visual Field tubeless" SV-VATS for tracheal surgery is still an open question in the field...

BACKGROUND AND AIMS: TheProSeal™ laryngeal mask airway (PLMA) and I-Gel™ are second-generation supraglottic airway devices (SADs). The Baska mask is a SAD having a non-inflatable cuff with a tendency to increase the perilaryngeal seal with an increase in airway pressures. This study compared the efficacy of I-Gel™, PLMA and Baska mask with respect to airway dynamics in patients scheduled for laparoscopic surgeries under general anaesthesia (GA). METHODS: Ninety patients, of American Society of Anesthesiologists physical status I and II, aged 20-65 years scheduled for laparoscopic cholecystectomy under GA were enroled...

BACKGROUND: Conflicting outcomes have been reported for the i-gel™ and laryngeal mask airway (LMA) ProSeal™ in children and adults during general anesthesia. Randomized controlled trials (RCTs) that yielded wide contrast outcomes between i-gel™ and LMA ProSeal™ were included in this meta-analysis. METHODS: Two authors independently identified RCTs that compared i-gel™ with LMA ProSeal™ among patients receiving general anesthesia by performing searches in EMBASE, Cochrane, PubMed, and ScienceDirect...

INTRODUCTION: ProSeal-Laryngeal Mask Airway™ (P-LMA™) is one of the commonly used laryngeal mask airways. Despite the proper insertion technique, suboptimal positioning and airway morbidity still occurs. This study explored the possibility of the operating table height position affecting successful P-LMA™ placement. METHODS: A total of 138 patients aged between 18 and 65 years old with the American Society of Anesthesiologists (ASA) I or II status, who required general anaesthesia and had no contraindication towards the use of P-LMA™, were recruited...

ProSealTM Laryngeal Mask Airway (PLMA) (Teleflex Medical, Westmeath, Ireland) is a versatile and popular reusable supraglottic airway device. The manufacturer advises maximum reuse of up to 40 times. However, excessive reuse of the device can cause rare complications. Here, we report a rather uncommon complication of intraoperative cuff rupture of a PLMA probably due to the combination of a forceful metal introducer tip insertion and nitrous oxide-based anaesthesia.

Insertion of the laryngeal mask airway (LMA) without muscle relaxant requires adequate obtundation of airway reflexes, which may otherwise lead to incorrect or failed LMA placement. This study compared topical lignocaine spray vs. intravenous (IV) fentanyl, during propofol induction for insertion of the ProSeal™ LMA (PLMA). This was a prospective, randomized, double blind study, in ASA I or II patients, for elective or emergency surgery. Seventy patients ( n = 70) who fulfilled the inclusion criteria were randomly assigned to receive IV fentanyl 2 mcg/kg or topical lignocaine spray 40 mg, prior to anesthesia induction with IV propofol (2-2...

Background and Aims: The LMA® ProSeal™, LMA® Supreme™ and Ambu® AuraGain™ are second-generation supraglottic airway devices (SADs) with integrated gastric access. In this study, we compared the clinical performance of these three devices in adults for controlled ventilation in anesthetized paralysed patients. Material and Methods: Two hundred and seventy adults, American Society of Anesthesiologists (ASA) Physical Status I-III, undergoing elective surgical procedures, were randomized into three groups with 90 patients in each: Group 1: LMA® ProSeal™, Group 2: LMA® Supreme™ and Group 3: Ambu® AuraGain™...

Background and Aims: Several supraglottic airway devices (SGD) are available nowadays. But none has been found to be better than Proseal laryngeal mask (PLMA) in terms of oropharyngeal leak pressure (OLP). We aimed to compare OLP of newly introduced Baska® Mask with PLMA in patients undergoing elective surgical procedures under general anesthesia. Material and Methods: Totally, 80 consecutive adult patients of either sex requiring general anesthesia were randomized into two groups Group B (Baska mask, n = 40) or Group P (PLMA...

INTRODUCTION: Ambu AuraGain and ProSeal laryngeal mask airway are second-generation supraglottic airway devices (SADs) with added advantage of gastric drain and better oropharyngeal sealing pressure. The primary objective was to study the difference in the gastric insufflation volume between Ambu AuraGain and ProSeal LMA in patients undergoing general anesthesia. METHODS: This randomized controlled trial involving 120 adult patients scheduled under general anesthesia were randomized into either Ambu AuraGain or LMA ProSeal group...

ProSeal laryngeal mask airway (PLMA) insertion is often difficult. Suction catheter-guided PLMA insertion was compared with the standard introducer tool-assisted technique. One hundred sixty female patients undergoing laparoscopic gynecologic procedures under general anesthesia were randomized into two groups-the suction catheter group (Group SC) and the introducer tool group (Group IT). First-attempt success rate, insertion time, manipulation required, incidence of trauma, and incidence and severity of throat discomfort were compared...

Transverse myelitis is a rare inflammatory neurological disorder of the spinal cord that damages the myelin covering the spinal cord and thus produces sensory, motor, and autonomic symptoms. A 26-year-old primigravida of 40 weeks gestation presented to the obstetric emergency of our hospital with complaints of weakness in both lower limbs and inability to walk for four days. A diagnosis of acute transverse myelitis was made, and due to fetal distress and arrest of labor in the second stage, an emergency cesarean section was planned...

Epoxy resin-based sealers are commonly used for successful endodontic treatment. This study aimed to evaluate the cytotoxicity and genotoxicity of epoxy resin-based sealers under unset and set conditions. Three epoxy resin-based sealers were used: Adseal, AH Plus, and Dia-Proseal. To test cytotoxicity, an agar overlay test and a 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay were performed using unset and set sealers on L929 mouse fibroblasts. The genotoxicity test of the comet assay was performed using the same cell line...

BACKGROUND: The value of positive end-expiratory pressure (PEEP) in maintaining oxygenation during ventilation with a laryngeal mask airway (LMA) mask is unclear. To clarify the potential benefit or harm to PEEP application during positive pressure ventilation with a ProSeal LMA® mask, we compared the effect of PEEP versus zero end-expiratory pressure (ZEEP) on gas leakage and oxygenation. We hypothesized that a PEEP of 8 mbar (8.2 cm H 2 O) would be associated with an increased incidence of gas leakage compared to ZEEP...

Aim: The aim of the study is to compare the push-out bond strength of bioceramic and epoxy sealers after using various final irrigants. Materials and Methods: Hundred single-rooted teeth were divided into two groups ( n = 50) according to the sealer used: Group A: Bio C (bioceramic sealer), Group B: Dia-Proseal (epoxy sealer). Each group was subdivided into five subgroups ( n = 10) according to the final irrigation protocol: Group A1 and B1 - 5% glycolic acid (GA), Group A2 and B2 - 17% GA, Group A3 and B3 - 0...
