Delirium is highly prevalent, occurring in 20% of acute hospital inpatients and up to 62% of surgical patients. It is a significant predictor of poor outcomes including mortality and institutionalisation, however it is often viewed as simply a marker of underlying illness and is frequently overlooked in older adults. Although delirium is commonly comorbid with dementia, it represents a more urgent diagnosis, requiring prompt intervention. ⋯ Appropriate treatment of delirium requires thorough investigation, management of the underlying illness, avoidance of complications and simplification of the care environment. Studies suggest a role for pharmacological prophylaxis, particularly in relation to anaesthetic and sedative agents used intra- and post-operatively. Furthermore, gathering evidence suggests that judicious use of antipsychotic medications may be helpful in delirium prevention and treatment.

The safety of the patient and its importance in a surgical setting is well recognised. However, in the literature far less emphasis is placed upon the safety of the surgeon and his/her team. This review discusses the risks to which a surgeon is exposed, including blood-borne pathogens, radiation exposure, biomechanical stresses and fatigue, and the adverse effects of diathermy fumes. Strategies addressing these risks are presented and recommendations to improve surgical team safety are offered.

An overview of intra-abdominal sepsis is necessary at this time with new experimental studies, scoring systems and audits on management outcomes. The understanding of the pathophysiology of the peritoneum in the manifestation of surgical sepsis and the knowledge of the source of pathogenic organisms which reach the peritoneal cavity are crucial in the prevention of intra-abdominal infection. Inter-individual variation in the pattern of mediator release and of end-organ responsiveness may play a significant role in determining the initial physiological response to major sepsis and this in turn may be a key determinant of outcome. The ability to identify the presence of peritoneal inflammation probably has the greatest influence on the final surgical decision. The prevention of the progression of sepsis is by early goal-directed therapy and source control. Recent advances in interventional techniques for peritonitis have significantly reduced the morbidity and mortality of physiologically severe complicated abdominal infection. In the critically ill patients there is some evidence that the prevention of gut mucosal acidosis improves outcome. The aim of this review is to ascertain why intra-abdominal sepsis remains a major clinical challenge and how a better understanding of the pathophysiology may enable its prevention and better management. ⋯ Electronic searches of the medline (PubMed) database, Cochrane library, and science citation index were performed to identify original published studies on intra-abdominal sepsis and the current management. Relevant articles were searched from relevant chapters in specialized texts and all included.

Continuous monitoring of the recurrent laryngeal nerve in thyroid surgery: a critical appraisal.
Intraoperative neuromonitoring (IONM) contributes in several ways to recurrent laryngeal nerve (RLN) protection. Notwithstanding these advantages, surgeons must be aware that the current, intermittent, mode of IONM (I-IONM) has relevant limitations. To overcome these I-IONM limitations, a continuous IONM (C-IONM) technology has been proposed. ⋯ RLN traction injury is still the most common cause of RLN injury and is difficult to avoid with the application of I-IONM in thyroid surgery. C-IONM is useful to prevent the imminent traction injury by detecting progressive decreases in electromyographic amplitude combined with progressive latency increases. C-IONM seems to be a technological improvement. Likely, C-IONM by vagal nerve stimulation should enhance the standardization process, RLN intraoperative information, documentation, protection, training, and research in modern thyroid surgery. Although C-IONM is a promising technology at the cutting edge of research in thyroid surgery, we need more studies to assess in an evidence-based way all its advantages.

The aim of this meta-analysis is to assess the association between obesity and risk of surgical site infections (SSI) risk in orthopedics. ⋯ Our meta-analysis indicates that obesity had about twofold increased risk of surgical site infections risk in orthopedics. However, this conclusion should be verified by further well designed prospective cohort studies.
