RESUMO
INTRODUCTION: Timing to resume feeds after percutaneous endoscopic gastrostomy (PEG) placement continues to vary among US trauma surgeons. The purpose of this study was to assess differences in meeting nutritional therapy goals and adverse outcomes with early versus late enteral feeding after PEG placement. METHODS: This retrospective review included 364 trauma and burn patients who underwent PEG placement. Data included patient characteristics, time to initiate feeds, rate feeds were resumed, % feed volume goals on postoperative days 0-7, and complications. Statistical analysis was performed comparing two groups (feeds ≤ 6 h versus > 6 h) and three subgroups (< 4 h, 4-6 h, ≥ 6 h) based on data quartiles. Chi-square/Fisher's exact test, independent-samples t-test, and one-way analysis of variance were used to analyze the data. RESULTS: Mean time to initiate feeds after PEG was 5.48 ± 4.79 h. Burn patients received early feeds in a larger proportion. A larger proportion of trauma patients received late feeds. The mean % of goal feed volume met on postoperative day 0 was higher in the early feeding group versus the late (P < 0.001). There were no differences in adverse events, even after subgroup analysis of those who received feeds < 4 h after PEG placement. CONCLUSIONS: Patients with early initiation of feeds after PEG placement achieve a higher percentage of goals on day 0 without an increased rate of adverse events. Unfortunately, patients routinely fall short of their target tube feeding goals.

BACKGROUND AND OBJECTIVES: Enoxaparin inactivates factor Xa via a complex formed after binding to circulating anti-thrombin III. This mechanism is reported not to alter hemostatic measures such as clotting time, PT, or PTT. To date, no clinical trials have shown a causal relationship between the clinical/pharmacological effects of enoxaparin on international normalized ratio (INR). The aim of our study is to show the clinical effect of enoxaparin on INR. METHODS: Patients (N = 350) were reviewed from our prospective IRB approved databases undergoing gastroesophageal or hepatobiliary surgeries. INR levels were recorded for 6 days: pre-operative to 5 days after surgery. RESULTS: Patients (N = 289) received enoxaparin daily starting post-operative day 1, while 61 patients who did not receive enoxaparin were used as controls. The mean post-operative INR in both the 30 and 40 mg groups were both significantly higher than the mean post-operative INR of the control group (P = 0.015 and P = 0.00075, respectively); however postoperative hemoglobin levels were not significantly lower in the enoxaparin versus control. CONCLUSION: This is the first clinical evidence of the effect of enoxaparin on INR in patients undergoing abdominal surgeries for malignancies. We demonstrate an increase in the INR for patients who received enoxaparin for post-operative VTE prophylaxis.
