Background Total Intravenous Anaesthesia (TIVA) with propofol infusion
is done by manual co’ntrolled infusion (MCI) or by target-controlled
infusion (TCI) devices. This is a comparative study of MCI/TCI
administration. Method In this randomized controlled trial, Anaesthesia
was induced with propofol 1%, using a target blood concentration of 5
Meg/ml in the TCI group or at a dose of 1.5 mg/kg at an infusion rate of
1200 ml/h in the MCI group. Subsequently, a step-down maintenance
regimen (10, 8 and 6 mg/kg/h at 10-min interval) was commenced for the
MCI group. Primary outcome was the time to induction of anaesthesia in
both groups. Data was analysed using Statistical Package for Social
Sciences (SPSS) version 20.0. Results 52 patients were recruited into
the study. The duration of induction of anaesthesia in the TCI group
compared to the MCI group was (94.62 ± 11.34 sec vs. 79.50 ±16.23 sec, p
= 0.001). The induction dose of propofol TCI against MCI was (118.00 ±
22.33 mg vs.133.04 ± 20.58 mg, p = 0.015). Both groups were comparable
in terms of total dose of propofol (I 152.92 ± 234.47 mg vs. 1014.97 ±
264.18 mg, p = 0.052), recovery time (8.45 ± 2.13 min vs. 7.86 ± 2.05
min, p = 0.314), haemodynamic parameters and incidence of adverse
events. Conclusion Manual controlled infusion was comparable to target
controlled infusion for the induction and maintenance of general
anaesthesia using propofol; providing similar quality and ease of
anaesthesia as a viable option in resource challenged settings.
