Impact of Omega-3 Fatty Acids on Lactate

NCT ID: NCT00929461

Last Updated: 2009-11-25

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Study Classification: INTERVENTIONAL

Brief Summary

Pre- and intra-operative nutritional support in patient undergoing major surgery results in decreased morbidity and mortality. Studies investigating the role of omega-3 fatty acids in these patients are increasing. Some are focused on perfusion at the cellular level. This study was undertaken to address the effect of postoperative administration of omega-3 fatty acids on cellular hypoperfusion associated with major gastric surgery.

Study Groups

Omega-3 group

All patients received TPN for 5 days postoperatively, according to a standard protocol: 3 g/kg BW glucose (5% Dextrose in Ringer's Lactate, Biosel, Istanbul), 1.2 g/kg BW amino acids (Aminosteril 10%, Fresenius-Kabi) and 0.8 g/kg BW omega-6 fatty acids (Lipovenoes® 10%, Fresenius-Kabi) were provided to both groups through an indwelling central venous catheter. In the omega-3 group, the lipid content of TPN was replaced partially by omega-3 fatty acids (Omegaven®, Fresenius-Kabi) up to 0.2 g/kg BW per day.

Group Type: OTHER

Lipovenoes® 10% and Omegaven®,

Intervention Type: DRUG

All patients received TPN for 5 days postoperatively, according to a standard protocol: 3 g/kg BW glucose (5% Dextrose in Ringer's Lactate, Biosel, Istanbul), 1.2 g/kg BW amino acids (Aminosteril 10%, Fresenius-Kabi) and 0.8 g/kg BW omega-6 fatty acids (Lipovenoes® 10%, Fresenius-Kabi) were provided to both groups through an indwelling central venous catheter. In the omega-3 group, the lipid content of TPN was replaced partially by omega-3 fatty acids (Omegaven®, Fresenius-Kabi) up to 0.2 g/kg BW per day.

Omega 3 + Omega 6 group

All patients received TPN for 5 days postoperatively, according to a standard protocol: 3 g/kg BW glucose (5% Dextrose in Ringer's Lactate, Biosel, Istanbul), 1.2 g/kg BW amino acids (Aminosteril 10%, Fresenius-Kabi) and 0.8 g/kg BW omega-6 fatty acids (Lipovenoes® 10%, Fresenius-Kabi) were provided to both groups through an indwelling central venous catheter.

In the omega-3 group, the lipid content of TPN was replaced partially by omega-3 fatty acids (Omegaven®, Fresenius-Kabi) up to 0.2 g/kg BW per day.
