TITLE A PROSPECTIVE RANDOMIZED COMPARATIVE STUDY OF I-GEL VERSUS BASKA MASK IN PATIENTS RECEIVING GENERAL ANAESTHESIA SUMMARY
TYPE OF STUDY:
A Prospective
randomized comparative study.
STUDY POPULATION:
Patients posted
for elective surgeries under general anaesthesia lasting for 1 to 3 hours at PIMS
were included in our study.
SAMPLE SIZE:
Fifty patients were
randomized into two groups of twenty five each.
PERIOD OF STUDY:
October 2018 to
April 2020.
OBJECTIVES:
1.
To evaluate the
oropharyngeal sealing pressure (OSP) of i-gel and baska mask.
2.
The ease of
insertion (assessed by the duration of time taken to insert them successfully
and the number of insertion attempts).
3.
To determine the
success rate of insertion based on positioning of the i-gel and baska mask
confirmed by boroscope.
4.
To detect the
hemodynamic responses induced by airway insertion (blood pressure, heart rate,
oxygen saturation and end-tidal carbon dioxide (EtCO2).
5.
The incidence of
postoperative complications such as the presence of laryngospasm on emergence,
blood on the mask, sore throat.
METHODS:
Fifty
patients posted for elective surgery under General Anaesthesia lasting for 1 to
3 hours were enrolled and randomized into two groups I and B.
1. Group I – I gel was used
2. Group B – Baska mask was used
OUTCOME MEASURES:
1. Oropharyngeal Sealing Pressure
2. Number of Attempts
3. Grade of Ease of Insertion
4. Duration of Insertion
PARAMETERS MONITORED:
The following parameters were recorded at the
time of insertion and every minute for the first 5 minutes and then, every
5mins for 15 minutes after successful insertion-
1. Heart and Blood pressure
2. EtCO2 and SpO2
The following parameters
are noted after extubation–
1. Laryngospasm
2. Blood staining on the device or in mouth
during suction.
3. Sore throat at half an hour after extubation,
2nd hour, 4th hour, 6th hour and 24 hours.
RESULTS:
· The Oropharyngeal Sealing Pressure was more
with Group B (29.4 cm of H2O) than Group I (26.32 cm of H2O).
· Number of Attempts of Insertion and Grade of
Ease of Insertion in both the groups were similar and had no statistical
difference.
· Mean duration of insertion was less in Group I
(13.28 s) than Group B (13.80 s), but statistically not significant.
· Parameters like blood pressure, heart rate,
SpO2 and ETCO2 were compared and no statistical
difference.
· No complications occurred in either group.
CONCLUSION
•
Oropharyngeal
sealing pressure with Baska mask was better when compared with I gel (P <0.042).
•
Time taken to
insert was similar in both the groups.
•
But ease of
insertion and number of attempts of insertions were similar in both the groups.
•
There was no
haemodynamic changes in both the groups within the study period.
•
There were no
complications with either of the SAD’s. |
