Impact of a bladder scan protocol on discharge efficiency within a care pathway for ambulatory inguinal herniorraphy.

BACKGROUND: Postoperative urinary retention (POUR) is a common complication of ambulatory inguinal herniorraphy, with an incidence reaching 38%, and many surgeons require patients to void before discharge. This study aimed to assess whether the implementation of a bladder scan-based voiding protocol reduces the time until discharge after ambulatory inguinal herniorraphy without increasing the rate of POUR. METHODS: As part of a perioperative care pathway, a protocol was implemented to standardize decision making after elective inguinal hernia repair (February 2012). Patients were assessed with a bladder scan, and those with <600 mL of urine were discharged home, whereas those with more than 600 mL of urine had an in-and-out catheterization before discharge. The patients received written information about urinary symptoms and instructions to present to the emergency department if they were unable to void at home. An audit of scheduled outpatient inguinal hernia repairs between October 2011 and July 2012 was performed. Comparisons were made using the t test, Fisher's exact test, and Wilcoxon rank sum test where appropriate. Statistical significance was defined a priori as a p value lower than 0.05. RESULTS: During the study period, 124 patients underwent hernia repair: 60 before and 64 after implementation of the protocol. The findings showed no significant differences in patient characteristics, laparoscopic approach (35 vs. 33%; p = 0.80), proportion receiving general anesthesia (70 vs. 73%; p = 0.67), or amount of intravenous fluids given (793 vs. 663 mL; p = 0.07). The proportion of patients voiding before discharge was higher after protocol implementation (73 vs. 89%; p = 0.02). The protocol had no impact on median time to discharge (190 vs. 205 min; p = 0.60). Only one patient in each group presented to the emergency department with POUR (2%). CONCLUSION: After ambulatory inguinal herniorraphy, implementation of a bladder scan-based voiding protocol did not result in earlier discharge. The incidence of POUR was lower than reported in the literature.

Successful DCD kidney transplantation using early corticosteroid withdrawal.

Organs from donors after cardiac death (DCD) are being increasingly utilized. Prior reports of DCD kidney transplantation involve the use of prednisone-based immunosuppression. We report our experience with early corticosteroid withdrawal (ECSW). Data on 63 DCD kidney transplants performed between 2002 and 2007 were analyzed. We compared outcomes in 28 recipients maintained on long-term corticosteroids (LTCSs) with 35 recipients that underwent ECSW. DGF occurred in 49% of patients on ECSW and 46% on LTCS (p=0.8). There was no difference between groups for serum creatinine or estimated GFR between 1 and 36 months posttransplant. Acute rejection rates at 1 year were 11.4% and 21.4% for the ECSW and LTCS group (p=0.2). Graft survival at 1 and 3 years was 94% and 91% for the ECSW group versus 82% and 78% for the LTCS group (p>or=0.1). Death censored graft survival was significantly better at last follow-up for the ECSW group (p=0.02). Multivariate analysis revealed no correlation between the use of corticosteroids and survival outcomes. In conclusion, ECSW can be used successfully in DCD kidney transplantation with no worse outcomes in DGF, rejection, graft loss or the combined outcome of death and graft loss compared to patients receiving LTCS.

The outcomes of the elderly in acute care general surgery.

INTRODUCTION: Elderly patients form a growing subset of the acute care surgery (ACS) population. Older age may be associated with poorer outcomes for some elective procedures, but there are few studies focusing on outcomes for the elderly ACS population. Our objective is to characterize differences in mortality and morbidity for acute care surgery patients >80 years old. METHODS: A retrospective review of all ACS admissions at a large teaching hospital over 1 year was conducted. Patients were classified into non-elderly (<80 years old) and elderly (≥80 years old). In addition to demographic differences, outcomes including care efficiency, mortality, postoperative complications, and length of stay were studied. Data analysis was completed with the Student's t test for continuous variables and Fisher's exact test for categorical variables using STATA 12 (College Station, TX, USA). RESULTS: We identified 467 non-elderly and 60 elderly patients with a mean age-adjusted Charlson score of 3.2 and 7.2, respectively (p < 0.001) and a mortality risk of 1.9 and 11.7 %, respectively (p < 0.001). The elderly were at risk of longer duration (>4 days) hospital stay (p = 0.05), increased postoperative complications (p = 0.002), admission to the ICU (p = 0.002), and were more likely to receive a non-operative procedure (p = 0.003). No difference was found (p = NS) for patient flow factors such as time to consult general surgery, time to see consult by general surgery, and time to operative management and disposition. CONCLUSIONS: Compared to younger patients admitted to an acute care surgery service, patients over 80 years old have a higher risk of complications, are more likely to require ICU admission, and stay longer in the hospital.

Posterior mediastinal hematoma after a fall from standing height: a case report.

Posterior Mediastinal Hematomas (PMHs) secondary to a fall from standing height are uncommon, with only one previous case reported in the literature. We describe a case of a 78-year-old male with multiple medical comorbidities, who was transferred to Montreal General Hospital (MGH) with a posterior mediastinal hematoma (PMH) after sustaining a fall from standing height. On initial assessment, the patient was hemodynamically stable and complained of mild chest pain, dyspnea, fatigue, and diaphoresis. The patient's airway was secured via endotracheal intubation fearing impending respiratory compromise secondary to an enlarging PMH. The patient was admitted to ICU where over the next 3 days he was managed conservatively via careful monitoring of his hemodynamic and hematologic indices. Repeat CT scanning indicated reduction in size of the PMH. The patient was discharged on hospital day eight. This case describes the assessment, evaluation, and conservative management of PMH in a complicated patient receiving prior anticoagulation. A review of the literature regarding the epidemiology of PMH and the management of both unstable and stable PMHs is also presented.

Evaluating living kidney donors: relationship types, psychosocial criteria, and consent processes at US transplant programs.

We conducted a survey of 132 US kidney transplant programs to examine how they evaluate and select potential living kidney donors, focusing on donor-recipient relationships, psychosocial criteria, and consent processes. There is heterogeneity in donor-recipient relationships that are considered acceptable, although most programs (70%) will not consider publicly solicited donors. Most programs (75%) require a psychosocial evaluation for all potential living donors. Most programs agree that knowledge of financial reward (90%), active substance abuse (86%), and active mental health problems (76%) are absolute contraindications to donation. However, there is greater variability in how other psychosocial issues are considered in the selection process. Consent processes are highly variable across programs: donor and recipient consent for the donor evaluation is presumed in 57% and 76% of programs, respectively. The use of 13 different informed consent elements varied from 65% (alternative donation procedures) to 86% (description of evaluation, surgery and recuperative period) of programs. Forty-three percent use a 'cooling off' period. Findings demonstrate high variability in current practice regarding acceptable donor-recipient relationships, psychosocial criteria, and consent processes. Whether greater consensus should be reached on these donor evaluation practices, especially in the context of more expansive use of living donor kidney transplantation, is discussed.

The medical evaluation of living kidney donors: a survey of US transplant centers.

The use of living donors for kidney transplantation in the United States is common, and long-term studies have demonstrated the safety of donation by young, healthy individuals. However, transplant programs have little data to guide them in deciding which donors are unacceptable, and which characteristics are associated with kidney disease or poor psychosocial outcomes after donation. To document current practices in evaluating potential donors, we surveyed all US kidney transplant programs. Compared to a survey 12 years ago, medical criteria for donation are more inclusive in several areas. All responding programs now accept living unrelated donors. Most programs no longer have an upper age limit to be eligible. Programs are now more likely to accept donors with treated hypertension, or a history of kidney stones, provided that certain additional criteria are met. In contrast, medical criteria for donation are more restrictive in other areas, such as younger donor age and low creatinine clearance. Overall, significant variability remains among transplant programs in the criteria used to evaluate donors. These findings highlight the need for more data on long-term outcomes in various types of donors with potential morbidities related to donation.

Confluence of the right adrenal vein with the accessory right hepatic veins. A potential hazard in laparoscopic right adrenalectomy.

Confluent drainage of the right adrenal vein and large accessory right hepatic veins was encountered during a laparoscopic right adrenalectomy. In a review of previous reports of laparoscopic adrenalectomies we found no mention of this finding. However, an anatomic study reported that the right adrenal vein joins with an accessory right hepatic vein in as many as 22% of individuals. A complete understanding of the anatomic variations in the drainage of the right adrenal vein is required for the safe performance of laparoscopic right adrenalectomy.

Protein profiles of Capnocytophaga species.

Ninety-seven strains of Capnocytophaga isolated from the oral cavity and the type strains of C. ochracea, C. sputigena and C. gingivalis were compared by one-dimensional SDS-PAGE of whole cell proteins. The protein patterns were highly reproducible and were used as the basis for numerical taxonomic analysis. The clusters containing the type strains of C. ochracea and C. sputigena segregated at the 78% similarity level. Some of the eight clusters obtained at this level showed good correlation with grouping based on the results of biochemical testing for lactose and galactose fermentation and nitrate reduction. No consistent association was found between protein profiles and colony type, size or colour or cell length but all agar-adherent colony types segregated into a single cluster.
