Summary

This study was conducted in 120 patients aged from 54-65 years scheduled for elective valve replacement surgeries. Patients were randomly allocated to nitro glycerine or PGI2 groups. Patients of nitro glycerine group received nebulized nitro glycerine at a rate of 2.5-5 mcg/kg/min (5 mg, 1 mg/ml) over 10 minutes by ultrasonic nebuliser. Patients of PGI2 group received nebulized PGI2 (epoprostenol), 20000 ng/ml (20000 ng/ml in 60 ml syringe was attached to an intravenous pump which delivers a titrating rate of 8 ml/h . The primary outcome was mean pulmonary artery pressure. The secondary outcomes included mean arterial blood pressure (MAP) (mmHg), PaO2/FiO2 ratio, cardiac index (CI) (l/min/m2) right ventricular ejection fraction (RVEF), central venous pressure(CVP) , 30-day mortality rate and the incidence of complications such as facial flushing, hypotension and re-exploration for bleeding.

Conditions

  • Pulmonary Hypertension

Interventions

DRUG

Nitroglycerin

Patients of nitroglycerine group received nebulized nitro glycerine (a vial contains 50 mg nitroclycerine ), its starting concentration was 200 mcg/ml with nitro glycerine was delivered at 2.5-5 mcg/kg/min (5 mg, 1 mg/ml) over 10 minutes by ultrasonic nebuliser connected to the inspiratory limb of the breathing circuit

DRUG

PGI2

Patients of PGI2 group received nebulized PGI2 (epoprostenol), 20000 ng/ml (Flolan; Glaxo Wellcome Inc, Research Triangle Park, NC) (60 ml syringe of PGI2 with concentration 20000 ng/ml was attached to an intravenous pump which delivers a titrating rate of 8 ml/h to the nebulizer compartment (MiniHEART nebulizer; Westmed, Tucson, Ariz) fixed to the inspiratory limb of the breathing circuit or to the face mask with venturi accessory for sprinkling. The nebulizer was filled with 15 ml PGI2 with nebulized oxygen flow rate 3 litres
