“…The haemodynamic response to insertion of i-gel was significantly less than that for endotracheal intubation (2,19) and is a reflection of an increase in sympathoadrenal activity due to oropharyngeal and laryngotracheal stimulation (20). I-gel has a soft gel thermoplastic elastomer cuff and may prevent stress stimulation.…”

“…Mean blood pressure [ Ismail et al, [28] measured Intraocular pressure (IOP), Haemodynamic responses in 60 patients divided into three groups receiving LMA, i-gel, Endotracheal tube and they came into a conclusion that i-gel insertion provides better stability of IOP and haemodynamic system when compared with LMA or E.T tube insertion. Our result was also similar with that of Ismail et al, Placement of any supraglottic airway device is expected to be associated with changes in HR, SBP, DBP and MABP possibly due to stimulation of receptors on the wall of the pharynx, resulting in a reflex sympathetic response.…”

“…Use of LMA and tracheal tube resulted in signifi cant increase in intraocular pressure and hemodynamics compared to I-gel 7 . Present study also revealed that there is increase in heart rate and blood pressure compared to baseline and intergroup comparison also resulted in maximum response with tracheal tube and least with I-gel use.…”

Background: Despite use of adequate medications and techniques, tracheal intubation induces haemodynamic stress response, which can be minimized by using supraglottic airway devices instead of tracheal tube in elective surgical cases with adequate oxygenation and ventilation. Objectives: To compare haemodynamic variables and ventilation parameters of I-gel and laryngeal mask airway with tracheal intubation during laparoscopic surgery. Methods: This is a prospective randomized comparative study among 90 cases of American Society of Anesthesiologists physical status class I and II, undergoing laparoscopic cholecystectomy, who were equally divided into three groups of 30 patients each: I-gel group, Laryngeal mask airway group and Tracheal tube group. Randomization was done with pick up of cards from sealed envelope. Basal readings of heart rate, systolic, diastolic and mean arterial pressure were recorded and these parameters were measured again before airway device placement, one, three and fi ve minutes after airway manipulation, during carboperitoneum creation and before and after extubation. Oxygen saturation, end tidal CO 2 , airway pressure and inhaled and exhaled tidal volume and minute volume were monitored before, during and after carboperitoneum creation. Leak volume was calculated by deducing exhaled tidal volume from inhaled tidal volume. Statistical analysis (Analysis of variance test) was done to see the differences among the groups. Results: Haemodynamic perturbations were maximum with tracheal intubation and moderate with laryngeal mask airway while stable haemodynamics was observed with I-gel. Intra and inter-group comparison revealed signifi cant differences after use of airway devices and after removal as well. Regarding ventilatory response, oxygenation and ventilation was well maintained with maximum airway pressure of mean ± SD: 20.11 ±3.46, 20.24 ±4.42, 19.05±4.82 cmH 2 O during carboperitoneum creation in I-gel, laryngeal mask airway and tracheal tube group respectively and oxygen saturation of 98 to 100% and end tidal CO 2 level of 31-35 mmHg. In all groups, minute volume was well maintained and leak volume of 18.88±12.40, 17.13±13.32 and 20.89±12.20 ml were recorded in I-gel, laryngeal mask airway and tracheal tube group respectively during carboperitoneum creation. There was no statistically signifi cant difference among the groups at any time regarding the monitored parameters. Conclusion: Among the three airway management devices used during general anaesthesia with positive pressure ventilation, I-gel produced least haemodynamic stress response, both supraglottic devices can be used with proper size and placement with acceptable haemodynamics and ventilation during laparoscopic surgery.

Intraocular pressure and haemodynamic responses to insertion of the i-gel, laryngeal mask airway or endotracheal tube

Abstract: Insertion of the i-gel device provides better stability of IOP and the haemodynamic system compared with insertion of an endotracheal tube or LMA in patients undergoing elective non-ophthalmic surgery.
