Anestesia epidural para pleurodesis por toracoscopia: un estudio prospectivo de cohorte / Awake epidural anesthesia for thoracoscopic pleurodesis: A prospective cohort study

Antecedentes: Se ha sugerido que puede haber un beneficio al utilizar la anestesia epidural torácica con el paciente despierto (AETD) para procedimientos toracoscópicos de invasión mínima en pacientes críticos. Sometimos a prueba la hipótesis de que la AETD es superior a la anestesia general (AG) al comparar las complicaciones tempranas en este escenario. Métodos: Se realizó un estudio prospectivo de cohorte durante un período de 36 meses para comparar la AG con la AETD en pacientes con derrame pleural maligno programados para pleurodesis con talco por toracoscopia (PTT). Se analizaron las complicaciones pulmonares, cardíacas y renales, la mortalidad, la calidad de la analgesia y los eventos postoperatorios. Se realizaron análisis univariados y bivariados y se desarrollaron curvas de probabilidad de tiempo de sobrevida a fin de determinar una posible relación entre una técnica anestésica particular y las complicaciones postoperatorias. Se consideró significativo un valor de p<0,05. Resultados: Se incluyeron 47 pacientes en el análisis. Las características preoperatorias de los grupos fueron comparables (AG, n=24; AETD, n=23). La incidencia de complicaciones pulmonares (AG=19 [86%] vs. AETD=3 [14%]; RR: 6,0 [95%CI: 2,07-17,7]; p<0,001) y la severidad del dolor postoperatorio (EVA>8) a las 24h (AG=7 vs. AETD=1; RR: 6,7 [95%CI: 1,13-18,2]; p=0,023) fueron significativamente mayores cuando los pacientes recibieron AG. El tiempo necesario para suspender todo tipo de soporte ventilatorio y para la movilización sin mayores restricciones (AG=4 [3,5-5] vs. AETD=3 [2-3,5] días; p=0,029) y el tiempo de permanencia global (GA=10 [3,5-29,5] vs. ATEA=4 [3-15,2] días; p=0,003) fueron significativamente menores en el grupo que recibió AETD. Conclusiones: Nuestro estudio sugiere que la AETD no solamente es un método anestésico seguro para los pacientes de cáncer sometidos a PTT, sino que también se asocia con una reducción significativa de los eventos pulmonares postoperatorios y de la permanencia hospitalaria, y con un mejor control del dolor postoperatorio. Se requieren estudios aleatorizados para corroborar estos hallazgos.

Background: It has been suggested that there is some benefit when awake thoracic epidural anesthesia (ATEA) is used for minimally invasive thoracoscopic procedures in critical patients. We tested the hypothesis that ATEA is superior to general anesthesia (GA) when comparing early pulmonary complications in this setting. Methods: A prospective cohort study was carried out over a 36-month period, comparing patients with malignant pleural effusion scheduled for thoracoscopic talc pleurodesis (TTP) using GA vs. ATEA. Postoperative pulmonary, cardiac, and renal complications, death rate, quality of analgesia and events were analyzed. Univariate and bivariate analyses were performed and time survival probability curves were developed in order to find a possible relation between a particular anesthetic technique and postoperative complications. A p value of <0.05 was considered significant. Results: Forty-seven patientswere included in the analysis. Preoperative characteristicswere comparable between groups (GA n = 24; ATEA n = 23). Incidence of pulmonary complications [GA = 19 (86%) vs. ATEA = 3 (14%). RR 6.0 (95% CI 2.07-17.7); p < 0.001] and severity of postoperative pain (VAS > 8) at 24 h [GA = 7 vs. ATEA = 1 RR 6.7 (95% CI 1.13-18.2); p = 0.023] were significantly higher when patients received GA. Time required to absence of any postoperative ventilatory support and mobilization with no major restrictions [GA = 4 (3.5-5) vs. ATEA = 3 (2-3.5) days; p = 0.029] and global LOS [GA = 10 (3.5-29.5) vs. ATEA = 4 (3-15.2) days; p = 0.003] were significantly reduced in the ATEA group. Conclusions: Our study suggests that ATEA is not only a safe anesthetic approach for cancer patients undergoing TTP but is also associated with a significant reduction in pulmonary postoperative events, hospital stay, and a better postoperative pain control. Randomized studies are required to corroborate these findings.

Experience of two first level hospitals in the southwest region of Colombia on the implementation of the Panamerican Trauma Society International Trauma Registry.

OBJECTIVE: To describes the experience in the implementation of a TRS in two hospitals in Cali, Colombia. METHODS: The TRS includes prehospitalary, during hospitalization and discharging status information of each patient. Each hospital has an electronic data capture strategy. A three month Pilot-period descriptive analysis is presented. RESULTS: 3293 patients has been registered, 1626 (49.4%) from the Public hospital and 1613 (50.6%) from the Private one. 67.2% were men; the mean age ±SD was 30.5±20 years; 30.5% were less than 18 years. The overall mortality rate was 3.5%. The most frequent consulting cause were falls (33.7%); 11.6% of injuries are secondary to fire gunshot, and this group where mortality rate was 62%. CONCLUSION: It was determined the needing for the TRS implementation and the mechanisms to provide continuity. The registry becomes an information source for the investigation developing. It was identified the causes of consult, morbidity and death due to trauma that will allow a better planning of the emergency services and of the regional trauma system in order to optimize and reduce the attention costs. Based on optimal information system it will be able to present the necessary adjusts to redesign the Trauma and Emergencies Attention System in the Colombian South-West.

The 1-2-3 approach to abdominal packing.

BACKGROUND: Abdominal packing (AP) in damage-control laparotomy (DCL) is a lifesaving technique that controls coagulopathic hemorrhage in severely injured trauma patients. However, the impact of the duration of AP on the incidence of re-bleeding and on intra-abdominal infections in penetrating abdominal trauma is not clear. The objective of the present study was to evaluate the complications related to the duration of AP and to determine the optimal time for AP removal. METHODS: Prospectively collected/retrospectively analyzed data at an urban level I trauma center from January 2003 to December 2010 were used as the basis for this study. Inclusion criteria were adults (≥18 years old) with penetrating abdominal trauma, who had survived both the initial DCL procedure and their first re-laparotomy. All initial DCL patients included in the study underwent abdominal packing for coagulopathic hemorrhage control. The outcome measures of this study were re-bleeding after packing removal, intra-abdominal infection, and 30-day cumulative mortality. We considered time after packing as an independent variable. This was defined as the total amount of time (in days) that the packs were left in the patient's abdomen. Patients were grouped according to the duration in days of their AP in <1, 1-2, 2-3, and >3 days. RESULTS: Of 503 patients with penetrating abdominal trauma, 121 underwent DCL and AP. The mean age was 30.1± 11.5 years, and the male to female ratio was 9:1. The mean Acute Physiology and Chronic Health Evaluation (APACHE II) score was 17.6±7.2. The mean Injury Severity Score (ISS) score was 24.9±9.1. The right upper quadrant was packed in 39 (32.2%) patients, retroperitoneum in 70 (57.8%), pelvis in 13 (10.7%), and left upper quadrant in 9 (7.4%). Fifty-one patients (42.1%) had associated colon injuries and 58 (47.9%) had small bowel injuries. Twenty-six patients (21.5%) had AP<1 day, 42 patients (34.7%) had AP between 1 and 2 days, 35 patients (28.9%) had AP between 2 and 3 days, and 18 patients (14.8%) had AP>3 days. The re-bleeding rate in patients packed for 1-2 days compared to those packed for <1 day was a third lower, 14.3%, (95% confidence interval [95% CI]: 8.06, 20.5) versus 38.5% (95% CI: 25.4, 51.5). Conversely, an increasing trend toward intra-abdominal infection occurred as time after packing increased. The infection rate tripled from 16.7% (95% CI: 6.6, 26.7) to 44.4% (95% CI: 31.03, 57.7) when comparing 1-2 days versus >3 days. Overall mortality was 16.5%. Of these deaths, 8.26% were attributable to re-bleeding, and 13.2% to intra-abdominal infection. Deaths secondary to re-bleeding seemed to decrease with time of AP, whereas intra-abdominal infection deaths increased with time of AP (Chi square for trend p value=0.04). CONCLUSIONS: The present study suggests that AP used in the setting of DCL for coagulopathic hemorrhage control should not be removed prior to the first postoperative day because of the increased risk of re-bleeding. The ideal length of AP is 2-3 days, and AP left in longer than 3 days is associated with a significantly increased risk of infectious complications.

Safety of performing a delayed anastomosis during damage control laparotomy in patients with destructive colon injuries.

BACKGROUND: Recent studies report the safety and feasibility of performing delayed anastomosis (DA) in patients undergoing damage control laparotomy (DCL) for destructive colon injuries (DCIs). Despite accumulating experience in both civilian and military trauma, questions regarding how to best identify high-risk patients and minimize the number of anastomosis-associated complications remain. Our current practice is to perform a definitive closure of the colon during DCL, unless there is persistent acidosis, bowel wall edema, or evidence of intra-abdominal abscess. In this study, we evaluated the safety of this approach by comparing outcomes of patients with DCI who underwent definitive closure of the colon during DCL versus patients managed with colostomy with or without DCL. METHODS: We performed a retrospective chart review of patients with penetrating DCI during 2003 to 2009. Severity of injury, surgical management, and clinical outcome were assessed. RESULTS: Sixty patients with severe gunshot wounds and three patients with stab wounds were included in the analysis. DCL was required in 30 patients, all with gunshot wounds. Three patients died within the first 48 hours, three underwent colostomy, and 24 were managed with DA. Thirty-three patients were managed with standard laparotomy: 26 patients with primary anastomosis and 7 with colostomy. Overall mortality rate was 9.5%. Three late deaths occurred in the DCL group, and only one death was associated with an anastomotic leak. CONCLUSIONS: Performing a DA in DCI during DCL is a reliable and feasible approach as long as severe acidosis, bowel wall edema, and/or persistent intra-abdominal infections are not present.
