RESUMEN
Introduction: Intravesical Bacillus Calmette-Guérin (BCG) instillation is the most effective adjuvant therapy for superficial urinary bladder carcinoma, prolonging disease-free survival. Although it is usually well tolerated, moderate to severe local or systemic infectious complications, including sepsis involving multiple organs, may occur. Case report: We report the unusual case of a man in his mid '70s who presented with septic shock and severe acute respiratory failure requiring intubation. Lack of response to antibiotics, history of intravesical BCG instillation and consistent imaging findings led to further investigations, with bronchoalveolar lavage (BAL) fluid polymerase chain reaction (PCR) results indicating pneumonitis due to Mycobacterium bovis dissemination. Prompt anti-tuberculosis treatment combined with corticosteroids resulted in significant clinical and radiological improvement, supporting the diagnosis of disseminated BCG infection. Conclusions: Due to its non-specific clinical presentation and the relatively low diagnostic yield of conventional microbiological tests, a high index of suspicion is required for prompt diagnosis and treatment of systemic BCG infection. PCR-based assays for mycobacterial DNA identification may represent a valuable tool facilitating timely diagnosis of this uncommon, yet potentially life-threatening infection.
RESUMEN
Percutaneous central venous catheterization, although a widely used technique in ICU patients worldwide, is not devoid of complications even under real-time ultrasound guidance. Arterial puncture is a well-recognized complication, while unintended subclavian or carotid artery cannulations during attempted central venous catheterization are infrequent, but documented complications with potentially deleterious consequences. Recently, endovascular balloon tamponade has emerged as the preferred initial approach to repair inadvertent arterial cannulations. Herein, we present a case series of inadvertent arterial catheterization during an attempted ultrasound-guided access of the right internal jugular and the left subclavian vein that were successfully managed with endovascular balloon tamponade.
RESUMEN
We performed a prospective pilot study of subarachnoid anesthesia for kyphoplasty in 11 nonrandomized patients. Subarachnoid anesthesia was administered at the level of the best palpable intervertebral space below L3. Patients received intrathecally either hyperbaric or plain bupivacaine with or without fentanyl. Five patients experienced pain during the surgical procedure and received supplemental IV analgesia. One patient felt pain from the pressure on the ribs while in the prone position. The remaining patients were comfortable. In no patient was respiratory compromise or deep sedation observed. We conclude that subarachnoid anesthesia may be an adequate technique for kyphoplasty.

BACKGROUND: Postoperative Acute Kidney Injury (AKI) is a common and serious complication associated with significant morbidity and mortality. While several pre- and intra-operative risk factors for AKI have been recognized in cardiac surgery patients, relatively few data are available regarding the incidence and risk factors for perioperative AKI in other surgical operations. The aim of the present study was to determine the risk factors for perioperative AKI in patients undergoing major abdominal surgery. METHODS: This was a prospective, observational study of patients undergoing major abdominal surgery in a tertiary care center. Postoperative AKI was diagnosed according to the Acute Kidney Injury Network criteria within 48 h after surgery. Patients with chronic kidney disease stage IV or V were excluded. Logistic regression analysis was used to evaluate the association between perioperative factors and the risk of developing postoperative AKI. RESULTS: Eleven out of 61 patients developed postoperative AKI. Four intra-operative variables were identified as predictors of AKI: intra-operative blood loss (p = 0.002), transfusion of fresh frozen plasma (p = 0.004) and red blood cells (p = 0.038), as well as high chloride load (p = 0.033, cut-off value > 500 mEq). Multivariate analysis demonstrated an independent association between AKI development and preoperative albuminuria, defined as a urinary Albumin to Creatinine ratio ≥ 30 mg·g-1 (OR = 6.88, 95% CI: 1.43â»33.04, p = 0.016) as well as perioperative chloride load > 500 mEq (OR = 6.87, 95% CI: 1.46â»32.4, p = 0.015). CONCLUSION: Preoperative albuminuria, as well as a high intraoperative chloride load, were identified as predictors of postoperative AKI in patients undergoing major abdominal surgery.
RESUMEN
INTRODUCTION: External electrical cardioversion under hypnotics, even when combined with opioids, has been consistently described as distressing or painful. The main objective of the present study was to determine if adding an opioid to a hypnotic, in comparison to the same hypnotic alone, would decrease the incidence of unpleasant or painful recall during anaesthesia for external electrical cardioversion. METHODS: This was a single-centre, prospective, randomised, double-blinded clinical trial that took place from September 2011 to March 2012. Fifty-two adult patients with persistent atrial fibrillation, scheduled for external direct current cardioversion, were enrolled. Exclusion criteria were age >80 years, previous cardiac surgery, implanted pacemaker or defibrillator, and haemodynamic instability. Patients received intravenously either (group EF) fentanyl 50 g and after 60 s etomidate 0.1 mg/kg, or (group E) only etomidate 0.1 mg/kg. If the patients did not lose their eyelid reflex, repeated doses of etomidate 4 mg were given. Cardioversion was attempted with an extracardiac biphasic electrical shock from 200 to 300 J, at most three times. The primary endpoint was recall of something unpleasant or painful. Secondary outcome measures were predictors of the requirement for repeat doses of etomidate, and the number of shocks needed. RESULTS: Fifty-one patients (35 male, 16 female), aged 62.1 ± 10.2 years, completed the study. There were no differences between group EF and group E regarding recall (unpleasant recall 0 vs. 2 patients, p=0.235; painful recall 1 vs. 0 patients, p=0.510). The administration of etomidate alone was a significant predictor for subsequent repeated doses of etomidate (p=0.049, odds ratio 4.312, 95% confidence interval 1.007-18.460). The number of shocks needed to restore sinus rhythm did not differ between the groups (p=0.846). CONCLUSIONS: In the present study, the addition of fentanyl to etomidate did not diminish distressing or painful experience during anaesthesia for external cardioversion.
