RESUMEN

BACKGROUND: Temporary abdominal closure (TAC) surgical technique relates to a procedure in which the post-surgical abdominal wall remains open in certain indications. The Bogota bag (BB) technique is a tension-free TAC method that covers the abdominal contents with a sterilized fluid bag. There are very few reports of pediatric patients treated with this technique. OBJECTIVES: To describe our institution's 15 years of experience using the BB technique on pediatric patients. METHODS: A retrospective cohort study describing our experience treating patients with BB was conducted. The medical files of 17 pediatric patients aged 0-18 years were reviewed. RESULTS: Between January 2000 and December 2014, 17 patients were treated with BB at our medical center (6 females, median age 12 years). Indications for BB were a need for a surgical site re-exploration, mechanical inability for primary abdominal closure, and high risk for ACS development. Median BB duration was 5 days and median bag replacement was 2 days. Median ICU length of stay (LOS) was 10 days and hospital LOS was 27 days. The ICU admission and BB procedure was tolerated well by 6 patients who were discharged home without complications. Of the remaining 11 patients, 6 patients died during the admission (35%) and the others presented with major complications not related to the BB but to the patient's primary disease. CONCLUSIONS: This report represents the largest series of children treated with BB. The technique is simple to perform, inexpensive, and has very few complications.

RESUMEN

BACKGROUND: We evaluated the effect of LF 18-1505T, a novel nonpeptide bradykinin type-2 receptor antagonist, on brain edema and neurologic severity score (NSS) after closed head trauma (CHT). METHODS: There were 132 rats anesthetized and assigned for sham or CHT; infusion of saline or LF 18-1505T (0.3, 1, 3, 10, or 30 microg x kg x min); and determination of neurologic outcome (brain water content and NSS) or physiologic variables (blood pressure, glucose concentration, etc.). RESULTS: Post-CHT brain water content was less with LF 18-1505T doses of 3 and 10 microg x kg x min (80.1 +/- 3.8 through 81.6 +/- 2.6%, mean +/- SD) than in the untreated group (84.6 +/- 1.9%, p < 0.01). Post-CHT NSS improved with doses of 3, 10, and 30 microg x kg x min (median, 7; range, 0-12 through median, 10; range, 8-18) as compared with that in the untreated group (median, 17; range, 14-23; p < 0.05). LF 18-1505T with or without CHT did not significantly alter physiologic variables. CONCLUSIONS: LF 18-1505T decreased brain edema and improved neurologic status after CTH in rats without significantly altering physiologic values.

RESUMEN

Adding furosemide (F) to mannitol causes a greater decrease of brain volume, intracranial pressure, and brain water content (BW) as compared with mannitol alone. We examined whether adding F to hypertonic saline (HS) causes less increase of BW early after closed head trauma (CHT) as compared with HS alone. With institutional approval, 125 rats underwent sham surgery or CHT and then immediately received no treatment, HS (1.2 g/kg, 3% solution), or HS + F (2 mg/kg). In groups 1-10 (n = 8/group), the percent BW content was determined at 30, 60, or 120 minutes. In groups 11-14 (n = 8/group), physiologic values were determined at 0, 30, 60, and 120 minutes. At 120 minutes, the increase of BW caused by CHT (sham = 78.9 +/- 0.6% and CHT = 81.5 +/- 2.2%, mean +/- SD) was prevented by HS + F (78.0 +/- 0.8%) but not by HS (80.7 +/- 2.2%). Both HS and HS + F similarly increased plasma osmolality and sodium concentration. Post-CHT hypotension and acidosis (30 and 60 minutes) and decrease of hemoglobin concentration (120 minutes) were less with HS + F than with HS. We conclude that adding F to HS decreases BW without causing more increase of osmolality and Na than that caused by HS alone.

RESUMEN

Computer simulations for the technique of estimating minimum alveolar anesthetic concentration (MAC) in patients (quantal design) suggest that incremental concentration changes and the number of crossovers affect MAC. We hypothesized that these variables may also apply to estimating MAC in rats (bracketing design). This study tested that hypothesis and also examined whether these variables might mask differences in MAC between groups in which MAC might be expected to differ (pregnant [P] versus nonpregnant [NP]). There were 2 cohorts (n = 27 and n = 30 rats). Each cohort included NP females, females in early P, and females in late P. MAC was tested by using an incremental concentration change of 0.20% and one within-subject crossover in the first cohort and by using an increment size of 0.10% and four crossovers in the second cohort. MAC was statistically significantly increased in the three groups in the second cohort (NP, 1.16 +/- 0.12; early P, 1.14 +/- 0.10; late P, 1.07 +/- 0.10; mean +/- sd) compared with values in the three comparable groups in the first cohort (NP, 0.95 +/- 0.06; early P, 1.01 +/- 0.09; late P, 0.93 +/- 0.13). Values did not differ among groups within each cohort. Post hoc simulations indicated that up to 36% of the difference between cohorts was due to increment size, with the balance due to experimental factors. Our findings confirmed the hypothesis that increment size affects estimates of MAC when a bracketing design is used.
