Spinal anesthesia is widely used for emergency and elective C/S delivery. However its main drawback is hypotension which may cause nausea, vomiting and cardiovascular collapse and loss of consciousness in mother as well as fetal hypoxia and acidosis due to placental hypo perfusion. AIMS AND OBJECTIVE: To compare the incidence of hypotension in intraoperative period and to compare the fetal outcome in two groups (Preloading and co loading group). STUDY DESIGN: Prospective randomized double blind study. MATERIALS AND METHOD: This study was conducted in the obstetric emergency OT of Malda Medical College. 100 primi gravid mothers aged between 18-29 years with ASA-1 physical status posted for emergency C/S for fetal distress was randomly allocated for either preloading (Group P) or co loading (Group C). RESULT AND ANALYSIS: Fluid requirement is significantly less in group C. There was no significant difference in the incidence of hypotension and ephedrine use. Fetal outcome in 1 min Apgar score in group C is significantly better as the baby could be delivered quickly in group C. CONCLUSION: Our study revealed that preloading can be safely avoided for spinal anesthesia in C/S for fetal distress. By using co loading method we can save valuable time required to deliver the baby and avoid circulatory overload without increasing the incidence of hypotension.

“…administration causes a signi®cant increase in central venous pressure, 55 pulmonary wedge pressure 78 and haemodilution, 136 with possible detrimental consequences from increased lung water content. 75 A more rational approach may therefore be the use of vasopressors instead of a highvolume preload during regional anaesthesia. A randomized study comparing an ephedrine infusion with a 15 ml kg ±1 crystalloid infusion in 54 patients undergoing elective gynaecological surgery with spinal anaesthesia, reported a signi®cantly lower incidence of hypotension with the ephedrine infusion (22 vs 55%).…”

“…During pregnancy, pulmonary vascular pressures alter little, but the hydraulic conductivity of the alveolarcapillary membrane increases and plasma oncotic pressure decreases (MacLennan 1986). These changes would be expected to cause an increase in total lung water during pregnancy, and this has been shown to be the case (MacLennan et al 1987). Beta-sympathomimetic agents appear to act by increasing the permeability of the alveolar-capillary barrier, and in one report of fatal pulmonary oedema precipitated by ritodnne, total lung water was found to be five times the normal value (MacLennan et al.…”
