Abstract
Maintenance of a patent airway is a primary responsibility of anaesthesiologists. Interruption of gas exchange, for even few minutes, can result in catastrophic outcomes such as brain damage or death. Closed claims analysis has found that vast majority (85%) of airway-related events involve brain damage or death, and as many as one third of deaths attributable solely to anaesthesia have been related to inability to maintain a patent airway.
Discovery of endotracheal intubation has not only made administration and maintenance of anaesthesia easy, but has also helped in saving several lives. Endotracheal intubation is usually carried out under direct vision made possible by direct laryngoscopy, which in a healthy patient, may not lead to serious complications.
Supraglottic airway devices (SAD) ventilate patients by delivering anaesthetic gases / oxygen above the level of the vocal cords and are designed to overcome the disadvantages of endotracheal intubation such as: soft tissue injury, tooth, vocal cords, laryngeal and tracheal damage, exaggerated haemodynamic response, and barotrauma. Advantages of supraglottic airway devices include: avoidance of laryngoscopy, less invasive for the respiratory tract, better tolerated by patients, increased ease of placement, improved haemodynamic stability in emergence, less coughing, less sore throat, hands free airway and easier placement by inexperienced personnel.
Since the development of LMA, many other supraglottic airway devices (SAD) have been introduced into the clinical practice of airway management, trying to offer a simple and effective alternative to ETT.
The present study was carried out to compare between BASKA MASK and CLMA for maintenance of airway during short surgical procedures under general anaesthesia with controlled ventilation as regards insertion success, efficacy of airway seal, adequacy of ventilation, haemodynamic responses, and complications of their use.
This study was done on forty adult patients of both sexes, ASA I or II, scheduled for short elective surgeries under controlled ventilation. They were randomly categorized into two equal groups (twenty patients each); BASKA MASK was used for group I, and CLMA was used for group II, for maintenance of airway during general anaesthesia with controlled ventilation. Their ages ranged from 19 to 40 years.
All the patients were assessed pre-operatively by detailed history taking, complete clinical examination, airway assessment, and routine laboratory investigations. On arrival to the operating room, patients were connected to the standard monitoring; including electrocardiograph, non-invasive arterial blood pressure, and pulse oximeter.
They were all subjected to the same anaesthetic protocol; pre-medicated by midazolam 0.02 mg/kg, followed by atropine sulphate 0.01 mg/kg intravenously, and all were pre-oxygenated with 100% oxygen for at least 3 minutes using a face mask.Induction of anaesthesia was commenced by the administration of fentanyl 1µg/kg then propofol 2 mg/kg intravenously. After loss of verbal communication, 0.5mg/kg atracurium was administrated. Ventilation was provided via face mask with 100% O2 and 2% isoflurane then the selected airway device
