Spinal (subarchanoid) anaesthesia is considered as the “Gold standard” technique for caesarean section. Hypotension is the most common side effect of neuraxial blocks in the obstetric patients. Prehydration is being commonly used as a preventive measure for hypotension. Colloid remains for a longer period within the intravascular space and colloid preload provides a sustained increase in central venous blood volume and cardiac output. The present study was aimed to compare haemodynamic changes following colloid preload and colloid co-load in patients who undergo elective caesarian section in preventing maternal hemodynamics following spinal anaesthesia.
After approval from IEC and obtaining informed consent from the participants, 75 (seventy five) parturient of ASA (American Society of Anesthesiologist) – I and II who were scheduled to undergo caesarean section under spinal anaesthesia were taken for this study and divided in to 3 groups based on receiving colloid preload, co-load and crystalloid drip. Data collected were analyzed using SPSS version 16 software for statistical significance and p <0.05 was regarded as significant.
Clinicodemographically all three groups were comparable. The incidence of hypotension with either Colloid Preload or Co-load is lower than the Control Group who received crystalloid drip (28% & 8% vs. 64% X2= 18.12 and p <0.05. However difference between Colloid Preload (28%) and Colloid co-load (28%) was not statistically significant (p > 0.05).
