Case Reports[Ultrasound-guided thoracic paravertebral block for closed loop ileostomy repair in severe COPD: a case report].
Ultrasound-guided thoracic paravertebral block is usually considered a good alternative to epidural thoracic for anesthesia and pain control in thoracic and breast surgery. Furthermore it has also been used during abdominal surgery lately, especially hepatic and renal surgery. However, its role is poorly defined in this context. The purpose of this report was to highlight the role of thoracic paravertebral block in providing effective anesthesia and analgesia during both the abdominal surgical intervention and pain control in post-operative period, avoiding possible complications which general anesthesia may arise, which are fairly common in patients with chronic obstructive pulmonary disease and similar comorbidities. ⋯ Thoracic paravertebral block may be a safe anesthetic method for abdominal surgery in those patients who would undergo potential severe complications by using general anesthesia.

Randomized Controlled Trial Comparative Study[Ultrasound dynamics of gastric content volumes after the ingestion of coconut water or a meat sandwich. A randomized controlled crossover study in healthy volunteers].
Adequate preoperative fasting is critical in preventing pulmonary aspiration of gastric content. We proposed to study the sonographic gastric content dynamics after the ingestion of liquid or solid food in healthy volunteers and confront it with current guidelines for preoperative fasting times. ⋯ Sonographic gastric dynamics for coconut water and a meat sandwich resulted in complete gastric emptying times higher and lower, respectively, than those suggested by current guidelines for preoperative fasting.
