The Effect of Ringer versus Haemaccel Preload on Incidence of Postoperative Nausea and Vomiting

INTRODUCTION

Postoperative nausea and vomiting (PONV) is the most common and unpleasant postoperative complication. There is much controversy on preoperative fluid therapy. The aim of this study was to examine the effect of crystalloid fluid (Ringer solution) versus colloid (Haemaccel solution) on the incidence of postoperative nausea and vomiting in patients receiving spinal anesthesia.

METHODS

In this double-blinded clinical trial, 46 patients were selected according to the inclusion and exclusion criteria. Patients were randomly allocated to one of two groups. The crystalloid group received Ringer solution at a volume of 7 ml/kg and colloid group received 7ml/kg of 3% Modified Gelatin (Haemaccel) as a preoperative intravenous bolus. We used a Verbal Rating Scale (VRS) for assessing the nausea and vomiting occurrence. Data were analyzed using SPSS software ver.13 and χ(2) test and independent t-test.

RESULTS

The result showed that the incidence of PONV was less frequent in both Ringer and Haemaccel groups, but the incidence of vomiting and the intensity of nausea was not significantly different in any time point after anesthesia.

CONCLUSION

We conclude that preoperative fluid administration decreases the incidence of PONV, and both Crystalloids (Ringer) and colloids (haemaccel) solution were found to be equivalent in prevention of PONV. Therefore using of either Ringer or haemaccel solution is recommended for prevention of PONV.

Stability Studies of Two Different Polygelin (Haemaccel and Gelofusine) According to ICH Guidelines

The stability of polygeline-based blood plasma expanders Haemaccel and Gelofusine were examined in context of their sensitivity to environmental factors, because drug stability is critical element in accurate and appropriate delivery of drug therapy to patients. This study was initiated to specifically and critically assess stability of Haemaccel and Gelofusine according to ICH guidelines with the aim of delivering safe, appropriate, acceptable, and efficacious administration of drug product in any situation. This study revealed that Haemaccel and Gelofusine are suitable for storage at different temperature and at different storage conditions until its expiry date, shelf life, or utility time, for their quality, safety, suitability, acceptability, and efficacy.

LAY ABSTRACT

Stability studies of two different plasma substitutes, Haemaccel and Gelofusine, were examined according to ICH guidelines for their expiry or utility time, because drug stability is very important element in accurate, suitable, and correct delivery of drug therapy to patients. The aim of present study is to deliver the safe, appropriate, acceptable, and right drug product in any situation. The results indicate negligible changes in different parameters during stability study, except for pH and viscosity. This study shows that both drug products are suitable for storage at different temperature and at different storage conditions till their expiry date or utility time, for their quality, safety, suitability, acceptability, and strength.
