Thiopentone Sodium Vs Ketofol: A Comparative Study In Electroconvulsive Therapy
Keywords:
N\AAbstract
BACKGROUND & AIM OF STUDY: We aim to compare THIOPENTONE SODIUM (TPS) and KETOFOL (a mixture of KETAMINE+PROPOFOL) as induction agents during ECT regarding their effects on ECT-induced hemodynamic changes, seizure duration and recovery parameters.
METHODS: 60 patients posted for electroconvulsive therapy (ECT) was allocated 30 each in two groups. Patient was premedicated with inj. glycopyrrolate 10 mcg/kg and induced with inj. Thiopentone sodium 3 mg/kg in Group A and Ketofol (Ketamine 0.5mg/kg + Propofol 0.5mg/kg) in Group B along with depolarizing muscle relaxant, inj. Succinyl choline 1mg/kg. Patient seizure duration, time for recovery, Richmond agitation sedation score, Modified Aldrete score, hemodynamics like heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, SPO2 were recorded at baseline and at 0 min, 3 min, 5 min, 10 min, 15 min, 20 min after induction. Parameters average was calculated and were compared by using chi-square test.
RESULTS: Seizure duration was better in Thiopentone sodium group(A) than Ketofol group(B) which was statistically significant with p=0.001.
Recovery time was better in Group B than Group A which was statistically significant with p=0.02. RASS, MAS were comparably better with Ketofol Group. Hemodynamics such as HR was significantly lesser in 3 min& 5 min with Group B(Ketofol). MAP was significantly lesser during induction& 20th min for group A(TPS).SPO2 was comparable in both groups. SBP at 0 min was lesser in Group A than Group B which was statistically significant. DBP at 10 min was lesser in group A than Group B which was statistically significant. In other minutes it was comparable between two groups.
CONCLUSION: Thiopentone sodium has significantly showed longer duration of seizure time. Ketofol showed significantly shorter duration of recovery time in patient undergone Electroconvulsive therapy.
