Interest in techniques and applications of the transversus abdominis plane (TAP) block has expanded exponentially since its introduction over ten years ago. The choice of techniques and approaches has been assisted with the availability of ultrasound, but the optimal injection for certain surgical incisions are not yet clear. A literature search was performed looking at anatomical and distribution studies, and clinical trials evaluating the effects of TAP blocks in patients undergoing abdominal surgery. ⋯ Clinical and contrast studies indicate that the landmark and ultrasound guided TAP blocks differ in their spread and mode of action. Regardless, both techniques provide effective analgesia for abdominal surgery. Further research is required to compare TAP blocks with epidural analgesia.

ReviewDiagnosis of pneumonia in mechanically ventilated patients. What is the meaning of the CPIS?
Ventilator associated pneumonia (VAP) is one of the most common nosocomial infections in critically ill patients, especially in those being mechanically ventilated. Beside increased healthcare costs due to prolonged hospital stay, VAP is associated with a consistently high morbidity and mortality. Although pathomechanisms leading to VAP are well known, it remains challenging to diagnose VAP accurately and in a timely manner. ⋯ Several evidence based strategies have been described for the diagnosis of ventilator associated pneumonia, potentially leading to better or faster treatment and thereby influencing the outcome. Current diagnostic approaches and the value of the CPIS are therefore considered within this article. A bundle approach, regarding time management and several diagnostic pathways should be evaluated in further studies.

Validation Of Visual Analogue Scale For Anxiety (Vas-A) In Preanesthesia Evaluation.
Anxiety is a relevant but still underscored perioperative problem. The Visual Analogue Scale for Anxiety (VAS-A) seems to be effective, fast and manageable, but has not been fully validated yet. The aim of this study is to validate VAS-A comparing it to, Corah's Dental Anxiety Scale (CDAS) Spielberger's State Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI). ⋯ Our study confirms that VAS-A is a reliable indicator of preoperative anxiety and may detect patients with depressive symptoms also. Values of VAS-A around 50 mm are a reliable threshold for a clinically meaningful level of preoperative anxiety.

Case ReportsMechanical and electrical equipment interference provokes a misleading Neurally Adjusted Ventilatory Assist (NAVA) EAdi signal. A technical note.
Neurally Adjusted Ventilatory Assist (NAVA) offers synchronized proportional pressure in accordance with the electrical activity of the diaphragm (EAdi). NAVA relies on the EAdi to trigger the respiratory cycle and then adjusts the ventilatory assist to the neural drive. The technique necessitates a catheter with bipolar microelectrodes positioned near the crural diaphragm where this signal can be captured. Capturing a reliable EAdi signal is a condition sine qua non for using NAVA as a mode of ventilation. The displayed signal represents the sum of the electrical activity of the muscle action potential of the diaphragm and is expressed in microvolts. ⋯ We illustrate that the detection and therefore interpretation of the EAdi signal during NAVA can be influenced by mechanical and electrical interference by other equipment used in the ICU or from endogenous leaking cardiac activity.
