About

Baska mask air way(BM) in comparative study with Proseal laryngeal mask airway (PLMA) regarding performance of Baska mask improves the safety and efficacy of airway management for in patients undergoing general anesthesia by mechanical ventilation confirmation of position by fiber optic view of glottis opening and success of gastric tube insertion , Airway sealing pressure, Leak fraction, insertion time and "overall insertion" success rates, and post-operative complications (airway trauma, hoarseness, sore throat and Dysphagia ).

Full description

Maintenance of a patent airway is a major responsibility for the anesthesiologists, interruption of gas exchange, even for a few minutes, can result in catastrophic outcomes such as brain damage or death.

Supraglottic airway devices are devices that ventilate patients by delivering anaesthetic gases/oxygen above the level of the vocal cord. Since the development of the laryngeal mask airway, many other supraglottic devices have been introduced in the clinical practice of airway management, trying to offer a simple and effective alternative to endotracheal tube.

However, following experience with such simple cases, clinicians soon become comfortable with more complex cases, such as cases of longer duration, cases with sicker patient reported favorable outcomes in safety profile, risk, ease of insertion, recovery of patients and cost analyses. However, there is an under reporting of complications aris¬ing during ventilation with this device and the risk factors associated with such complications in adult patients. These include Hypoxia, laryngospasm, and difficulty with insertion, suboptimal ventilation, bronchospasm, aspiration, desaturation, hy¬potension and conversion to intubation with ETT. These can be significantly serious and life threatening

Enrollment: 74 patients

---

74 participants in 2 patient groups

Group A Baska Mask

Active Comparator group

Description:

In which Baska Mask Airway (size 3,4,5) will used for ventilation according of patient body weight.Size selection is based on the manufacturer's recommendation of weight-based estimate plus clinical judgment. The Baska Mask is available in four sizes: size three (30 to 50 kg), size four (50 to 70 kg), size five (70 to 100 kg),The membranous cuff of the Baska Mask appears bulkier than the equivalent inflatable cuff on cuffed laryngeal masks. The mask can easily be decreased in size during insertion by compressing the proximal, firmer part of the mask below the airway tube, between the thumb and two fingers

Treatment:

Device: Group A : Baska Mask Airway

Group B Proseal Mask

Active Comparator group

Description:

In which Laryngeal Mask Airway- Proseal LMA (size 3,4,5) was used for ventilation according of patient body weight.Size selection is based on the manufacturer's recommendation of weight-based estimate plus clinical judgment.

Treatment:

Device: Group B: Proseal Laryngeal Mask Airway
