ReviewBasic guide to chronic pain assessment: from neurophysiology to bedside.
Chronic musculoskeletal pain is a highly prevalent condition that is commonly encountered in both general and specialist practice. Nonetheless, it still represents a significant challenge to the practitioners because of the lack of substantial evidence-based guidance. This review aimed to summarize the main pathophysiological mechanisms of chronic pain offering a mechanism-oriented approach to diagnosis and management. ⋯ Neuropathic features include both negative signs, such as reduced perception of vibration and touch, and positive symptoms, such as paroxysmal electric shock pain, due to ectopic discharge. These phenomena are the neurobiological basis of the commonly defined refractory chronic pain. Early detection and specific treatment of these mechanisms are required in order to restrain the reinforcement of pronociceptive remodeling of the nervous system.

Detection of strong inspiratory efforts from the analysis of central venous pressure swings: a preliminary clinical study.
Swings of central venous pressure (ΔCVP) may reflect those of pleural and esophageal (ΔPES) pressure and, therefore, the strength of inspiration. Strong inspiratory efforts can produce some harm. Herein we preliminarily assessed the diagnostic accuracy of ΔCVP for strong inspiratory efforts in critically-ill subjects breathing spontaneously. ⋯ In critically-ill subjects breathing spontaneously, ΔCVP recognized strong inspiratory efforts with acceptable accuracy. Even so, it sometimes largely differed from ∆PES.

Observational StudyLung ultrasound to monitor the development of pulmonary atelectasis in gynecologic oncologic surgery.
Atelectasis formation is considered the major cause of hypoxemia during general anesthesia (GA). Gynecologic oncologic surgery (GOS) often requires pneumoperitoneum and steep bed angulation that further reduce lung compliance by shifting bowels and diaphragm. The aim of our study was to assess the impact of intraoperative variables on lung aeration using lung ultrasound (LUS) score and their correlation with postoperative oxygenation in women undergoing GOS. ⋯ Aeration loss after GOS detected using LUS correlates with TR time, MV time, colloid infusion and worsening in oxygenation.
