The Bain co-axial circuit is fully established in general anaesthesia practice. A major concern is the potential malfunctioning of the circuit due to avulsion of the inner fresh gas delivery tube at the machine end of the circuit. The following case report presents a case in which a patient connected to the Bain circuit developed severe hypercapnia in the early intraoperative period due to the above mentioned defect.

Sixty ASA grade I & II adult patients of either sex were randomly assigned into two groups. Group I (n=30) for I-gel and Group P (n=30) for LMA – ProSeal. We assessed the airway sealing pressure, ease of insertion, success rate of insertion, ease of gastric tube placement, airway trauma by post operative blood staining of the device, tongue, lip and dental trauma, hoarseness, regurgitation / aspiration and cost effectiveness. Although the airway sealing pressure was higher with Group P (29.6 cm H2O) than with Group I (25.27 cm H20) (p < 0.05), but the airway sealing pressure of Group I was very well within the normal limit to prevent aspiration. The ease of insertion was more with Group I (29/30) than with Group P (25/30) (p < 0.05). The success rate of first attempt of insertion and ease of gastric tube placement was more with Group I (p > 0.05). Blood staining of the device & tongue, lip and dental trauma was more with Group P (p >0.05). There was no evidence of bronchospasm, laryngospasm, regurgitation, aspiration or hoarseness in either group. To conclude I-gel is a novel supraglottic device with an acceptable airway sealing pressure (25.27 cm H2O). It is easier to insert, requires less attempts of insertion, has easier gastric tube placement and is less traumatic as compared to LMA-ProSeal.
... [60][61][62] A careful check of the integrity of the co-axial circuit must be always done to prevent potential malfunctioning. [61][62][63] The single-limb circuit, which is the most used for home NIV, can be used with a calibrated leak either at the mask level (vented mask) or directly in the circuit for a use with non-vented masks. 21 With this circuit configuration, a minimum expiratory airway pressure of 4 cmH 2 O is mandatory to ensure an effective CO 2 washout. ...

... As Helmy et al., [11] Reza Hashemian et al., [12] and Chauhan et al. [13] observed significantly lower insertion times with i-gel™. Because the i-gel™ doesn't require cuff inflation, the time to establish an effective ~ 118 ~ airway was shorter, and since it doesn't need an introducer, the device can be simply pushed into place [14,15] . In this study LMA technique was more commonly used when GA was considered. ...
