Age and bupivacaine plasma concentrations following radical cystectomy.
Continuous epidural analgesia with bupivacaine for postoperative analgesia can increase its plasma concentrations. Whether this effect can be aggravated with increasing age is unknown. Therefore, bupivacaine concentrations were prospectively monitored in patients undergoing radical cystectomies. ⋯ In conclusion, continuous epidural administration of bupivacaine leads to increasing plasma concentrations. No age dependent differences in bupivacaine plasma concentrations could be found. Therefore, in our patients with intact liver function, we did not find a reason for an age-related restriction in the use of continuous epidural analgesia.

This case report illustrates the importance of proper assessment, management, and creation of an emergent surgical airway. Assessment after the establishment of surgical airways should include confirmation of correct surgical site and appropriate location and depth of tracheostomy, tracheal tube, or catheter placement within the trachea. Supraglottic surgical airway access, as occurred in this case, can lead to laryngotracheal and esophageal injury. Early recognition and appropriate management of this complication can increase the likelihood of preservation of voice and airway function and minimize the extent of esophageal injury.

Basic Critical Care Echocardiography by Pulmonary Fellows: Learning Trajectory and Prognostic Impact Using a Minimally Resourced Training Model.
The spread of basic critical care echocardiography may be limited by training resources. Another barrier is the lack of information about the learning trajectory and prognostic impact of individual basic critical care echocardiography domains like acute cor pulmonale determination and left ventricular function estimation. We thus developed a minimally resourced training model and studied the latter outcomes. ⋯ Basic critical care echocardiography training using minimal resources is feasible. New trainees can achieve reasonable competency in most basic critical care echocardiography domains after performing about 30 examinations within the first year. The relatively high prevalence of abnormalities and the significant association of acute cor pulmonale with ICU mortality support the need for basic critical care echocardiography training.

Case ReportsLong-term allergic dermatitis caused by sevoflurane: a clinical report.
Allergy to volatile anaesthetics is extremely rare, but capable of damaging the professional career. ⋯ The report aims to warn about the potential aetiological relationship between exposure to inhaled anaesthetics and allergic manifestations with cutaneous symptoms.

Left atrial pressure and its surrogate, pulmonary capillary wedge pressure (PCWP), are important for determining diastolic function. The role of transthoracic echocardiography (TTE) in assessing diastolic function is well established in awake subjects. The objective was to assess the accuracy of predicting PCWP by TTE and transesophageal echocardiography (TEE) during coronary artery surgery. ⋯ Doppler assessment of PCWP was neither sensitive nor specific enough to be clinically useful in anesthetized patients with mechanical ventilation. The fixed curve pattern of the interatrial septum was the best predictor of raised PCWP.
