BACKGROUND: Previous studies have shown Proseal LMA and I gel similar to endotracheal intubation in ventilatory ability in pediatric laparoscopic surgeries. AIMS: The primary aim of this study was to assess whether there is a significant difference in the oropharyngeal leak pressure between Ambu Auragrain, I-gel, and Proseal LMA during pediatric laparoscopic surgery. METHODS: In this randomized controlled trial, 90 male patients of American Society of Anesthesiologists physical status I aged between 6 months and 10 years who were scheduled for laparoscopic single-sided inguinal hernia repair were recruited and randomly allocated to three groups in which airway was secured with Ambu Auragain, I gel, or Proseal LMA...

BACKGROUND: Pediatric infraumbilical surgeries are often performed under general anaesthesia using different modes of ventilation through Laryngeal Mask Airway .Although controlled ventilation has been successfully used, very less studies have been done to compare them with spontaneous ventilation for short duration surgeries. AIMS: We tried to measure quantitave differences in haemodynamic and respiratory parameters and assess the recovery profile between controlled and spontaneous ventilation using Proseal LMA...

OBJECTIVES: Decalcification during orthodontic treatment is significantly increased. To prevent this negative impact, new treatments with sealants before bonding brackets are commonly been used. This systematic review discusses current knowledge on shear bond strength when using sealant before bonding. MATERIALS AND METHODS: A systematic review and meta-analysis were performed to identify studies that address shear bond strength after using a sealant before bonding brackets...

BACKGROUND AND AIMS: Optimum timing of laryngeal mask airway (LMA) removal after general anesthesia with isoflurane is debatable. The objective was to investigate the potential benefits of removing LMA ProSeal at ≤0.4 Minimum alveolar concentration (MAC) isoflurane over awake and "deep plane" extubation after short duration laparoscopic gynecological surgery. MATERIAL AND METHODS: In this prospective randomized trial 90 adult female patients undergoing elective laparoscopic surgery under general anesthesia using LMA ProSeal™ as airway device were included...

MATERIALS AND METHODS: This prospective randomized clinical trial included 40 orthodontic patients 12-17 years of age. One group had sealants placed on their anterior maxillary teeth, with reapplications every 3 months...

BACKGROUND: Laryngeal mask airways (LMAs) are widely used in paediatric anaesthesia. However, LMA use in neonatal age groups (younger than seven days) is limited because many anaesthesiologists prefer to use endotracheal tube in neonates. In this study, we compared the ProSeal LMA and endotracheal tube by measuring their performance, including ease of insertion via number of attempts for placement of device, total effective time for intubation and extubation, hemodynamic responses and perioperative complications...

BACKGROUND AND AIMS: Laparoscopic cholecystectomy is one of the commonly performed ambulatory surgeries. The selection of anesthetic agents for ambulatory surgeries should be done bearing in mind the need for early discharge. Opioids form an integral component of total intravenous anesthesia (TIVA) but their associated side effects may result in an increased hospital stay. Hence, we planned a study to compare the opioid (fentanyl) and non-opioid (dexmedetomidine) based technique of TIVA for laparoscopic surgery...

BACKGROUND: Tracheal intubation, a critical intervention, performed by paramedics for airway management in trauma, has an unacceptably low success rate due to difficult airway, restricted access, and inexperience. Thus, the use of supraglottic devices to achieve ventilation has gained popularity. AIMS: We aimed to compare the success rate, time to achieve ventilation, and ease of insertion of two popular supraglottic devices, ProSeal™ laryngeal mask airway (PLMA) and I-gel™, in simulated difficult airway with limited access in manikins in different positions which were supine, head against the wall, and sitting position like in car seat...

Numerous supraglottic airway device (SADs) have been designed for adults; however, their relative efficacy, indicated by parameters such as adequacy of sealing, ease of application, and postinsertion complications, remains unclear. We conducted a systematic review and network meta-analysis to evaluate the efficacy of various SADs. We searched electronic databases for randomized controlled trials comparing at least two types of SADs published before December 2019. The primary outcomes were oropharyngeal leak pressure (OLP), risk of first-attempt insertion failure, and postoperative sore throat rate (POST)...

BACKGROUND: During laparoscopic gynecological surgery, increased peak airway pressure (PAWP) can cause airway leak upon ventilation with the LMA® ProSeal™. We hypothesized that compared with the use of volume-controlled ventilation (VCV), the use of the AutoFlow® mode would decrease PAWP and airway leak during laparoscopic gynecological surgery with LMA ProSeal. METHODS: This single-center, randomized, controlled trial allocated 80 adult women undergoing elective laparoscopic gynecological surgery to one of two groups, namely, the AutoFlow group or the VCV group...

BACKGROUND: Use of an LMA ProSeal™ laryngeal mask airway (P-LMA; Teleflex) with no neuromuscular block is considered a safe alternative to tracheal intubation in short-duration paediatric laparoscopic surgery. However, few studies have evaluated surgical conditions of short-duration paediatric laparoscopic surgery using this anaesthetic technique. We assessed surgical conditions for paediatric laparoscopic inguinal hernia repair using P-LMA with and without neuromuscular block...

OBJECTIVE: To investigate the effect of tracheal intubation and ProSeal laryngeal mask airway (PLMA) on hemodynamics, oxygen saturation, peak airway pressure and adverse events during anesthesia for thyroid surgery. METHODS: 65 patients who underwent luminal thyroid surgery under general anesthesia were enrolled as the study subjects, and were divided into control group (30 patients, tracheal intubation) and experimental group (35 patients, PLMA) using random number table...

Objective: Since the inception of Bailey manoeuvre, various authors have advocated for the substitution of endotracheal tube (ETT) with a supraglottic airway device (SAD) before the emergence from anaesthesia. There is scant information about the ideal supraglottic device in the literature. The present study compared the Proseal laryngeal mask airway (LMA) with the I-gel SAD during the Bailey manoeuvre. The primary objective was to compare these for ease of insertion and adequate placement of supraglottic airway, whereas the secondary objective was comparison of haemodynamics following the Bailey manoeuvre...

BACKGROUND AND AIMS: The objective of this prospective randomized blinded study was to assess the safety and efficacy of the laryngeal mask airway (LMA) Supreme as compared with the LMA Proseal. MATERIAL AND METHODS: A total of 60 patients were randomised into two groups to either receive a Proseal LMA (PLMA) or Supreme LMA (SLMA) for airway management. The primary outcome was to measure oropharyngeal leak pressure (OLP) in both groups. The secondary outcomes were the measurement of insertion time, insertion success rate, fibreoptic grading, intracuff pressure, ease of ventilation, and airway pressure on standard ventilatory settings and postoperative complications...

BACKGROUND: Supraglottic airway device is presently the most common modality of airway management in children for short surgical procedures. The i-gel is one such novel supraglottic airway device with a non-inflatable cuff. The objective of the present study was to evaluate the efficiency of i-gel compared to LMA Proseal regarding oropharyngeal leak pressure, insertion time, ease of insertion, and fibreoptic view of larynx. METHODS: After obtaining ethical clearance and parental consent, 70 children aged 2-10 years, weighing 10-30 kg were randomised to receive LMA Proseal or i-gel for airway management...

Background and Aims: The Air-Q blocker (Cook gas LLC, Mercury Medical, Clearwater, FL, USA) is a relatively new supraglottic airway device (SAD) with capability to serve as a conduit for intubation. As there is limited data on Air-Q blocker, the present study was performed to compare the efficacy of Air-Q blocker and Proseal laryngeal mask airway (PLMA) in patients undergoing elective surgery. Methods: A total of 90 American Society of Anesthesiologists (ASA) physical status I and II patients were randomly allocated to Air-Q blocker or PLMA group...

OBJECTIVE: The objective of this study was to evaluate the in vitro performance of endodontic sealers in their freshly mixed and set forms. METHODS: The commercially used endodontic sealers (AH Plus, Dia-ProSeal, GuttaFlow 2, and Pulpdent Root Canal Sealer) were investigated and the chemical structure of freshly mixed and set sealers were assessed with Fourier transform infrared spectroscopy (FTIR). The surface morphology and elemental analysis were assessed with a scanning electron microscope (SEM) equipped with energy-dispersive X-ray spectroscopy...

Extraglottic airway devices (EAD) have revolutionized the perioperative airway management. The accuracy of clinical tests to identify malposition has been questioned by recent studies where fibreoptic evaluation identified various malpositions that were undiagnosed by a clinical test. Ultrasound (USG) has evolved to guide various airway interventions. However, USG is under-evaluated in the assessment of the EADs position. Our study aimed to compare clinical versus USG assessment of optimal placement of ProSeal laryngeal mask airway (PLMA)...

Introduction Severe postintubation tracheal stenosis (PITS) is a rare iatrogenic complication after endotracheal intubation. Case presentation A case of PITS in a 51-year-old male undergoing partial pericardiectomy with a principal diagnosis of tuberculous constrictive pericarditis. Within 6 hours of extubation, a second emergency intubation lasting 120 hours was performed. The patient reported exertional dyspnea 30 days after discharge. High-resolution tracheobronchial tree computed tomography with three-dimensional reconstruction revealed constriction of the tracheal lumen of more than 80% at the thyroid planar upper third of the trachea...
