Diplopia in facial fractures.

A prospective study was made on facial fracture patients who received treatment in Siriraj Hospital from 1 Jan 1997 to 31 Dec 1998. We recorded the types of fractures which involved the orbit, diplopia, operations and results. From the 675 facial fracture patients in this period, there were 256 cases that involved the orbit. Diplopia was found in 17 cases; Orbital floor fracture 8, Zygomatic fracture 4, Le Fort fracture 4, and Medial aspect fracture of maxilla 1. Ten cases were recent fractures and seven cases were old fractures. The floor of the orbits were explored in all cases and repaired with silastic sheath, except 2 severe enophthalmos cases whose medial wall and the floor of the orbits were repaired with titanium mesh. Diplopia disappeared after operation in 14 cases. Three cases still had minimal diplopia in the upward-gaze position and all of them were old fracture cases. The authors concluded that diplopia was found in 6.64 per cent of orbital fractures. Fracture of the floor of the orbit was the most common cause. An early operation will give a better result than late repair.

Metabolic and immune effects of dietary arginine, glutamine and omega-3 fatty acids supplementation in immunocompromised patients.

To evaluate the nutritional, metabolic and immune effects of dietary arginine, glutamine and omega-3 fatty acids (fish oil) supplementation in immunocompromised patients, we performed a prospective study on the effect of immune formula administered to 11 severe trauma patients (average ISS = 24), 10 burn patients (average % TBSA = 48) and 5 cancer patients. Daily calorie and protein administration were based on the patient's severity (Stress factor with the range of 35-50 kcal/kg/day and 1.5-2.5 g/kg/day, respectively) Starting with half concentration liquid immune formula through nasogastric tube by continuous drip at 30 ml/h and increasing to maximum level within 4 days. The additional energy and protein requirement will be given either by parenteral or oral nutritional support. Various nutritional, metabolic, immunologic and clinical parameters were observed on day 0 (baseline), day 3, 7, and 14. Analysis was performed by paired student-t test. Initial mean serum albumin and transferrin showed mild (trauma) to moderate (burn and cancer) degree of malnutrition. Significant improvement of nutritional parameters was seen at day 7 and 14 in trauma and burn patients. Significant increase of total lymphocyte count (day 7, P < 0.01), CD4 + count (day 7, p < 0.01), CD8 + count (day 7, p < 0.0005 & day 14, p < 0.05), complement C3 (day 7, p < 0.005 day 14, p < 0.01), IgG (day 7, and 14, p < 0.0005), IgA (day 7, p < 0.0005 & day 14, p < 0.05), in all patients. C-reactive protein decreased significantly on day 7 (p < 0.0005) and day 14 (p < 0.005). 3 cases of burn wound infection, one case of UTI and one case of sepsis were observed. Two cases of hyperglycemia in burn, 3 cases of hyperbilirubinemia in trauma, 10 cases of elevated LFT (5 trauma/5 burn), and one case of hyponatremia in cancer patients were observed. Two cases of nausea, 4 cases of vomiting, 5 cases of diarrhea (< 3 times/day), 2 cases of abdominal cramp, 1 case of distension were observed. The feeding of IMMUNE FORMULA was well tolerated and significant improvement was observed in nutritional and immunologic parameters as in other immunoenhancing diets. Further clinical trials of prospective double-blind randomized design are necessary to address the so that the necessity of using immunonutrition in critically ill patients will be clarified.

Early nutritional support in severe traumatic patients.

Multiple trauma is associated with altered metabolism, wasting of the lean body mass and compromised wound healing. Nutritional support is one way to improve the condition of these critically ill patients. We performed a prospective randomized study on the effect of early nutritional support in severely injured patients admitted to the Division of Traumatic Surgery, Siriraj Hospital between June 1992 and January 1994. Thirty-eight severe traumatic patients with ISS between 20-40 were randomly divided into control and study group. The 17 patients in the control group were treated in the conventional method with administration of hypo caloric intravenous regimen and supplement with oral diet as soon as the bowel function was returned. The 21 patients of the study group were fed either by enteral or parenteral feeding or both with an appropriate caloric and protein requirement as soon as hemodynamic status was stabilized. We found the study group had a lower mortality rate, a lower complication rate, a shorter period of ICU stay, and an earlier weaning from the ventilator than the control group. The study group also lost less weight than the control group. Nitrogen balance in the study group was significantly lower than the control group.
