Orthopedic bedside procedures commonly are performed and are appropriate. As the complexity of patient needs increases and resources are stretched, more patient care, including orthopedic procedures, will be performed in cost-effective but safe environments such as the monitored intensive care setting. ⋯ The decision to perform a specific procedure on a specific patient in a specific environment requires careful consideration of the risk to benefit ratio. This consideration should involve the patient, the physicians, and the entire health care team.

The improved technical sophistication of laparoscopy offers an attractive highly accurate diagnostic modality at the bedside for critically ill patients who are confined to the ICU and intensive monitoring unit and who are in need of timely abdominal evaluation. If the surgeon understands the physiologic effects of peritoneal insufflation and considers them during the procedure, the patient tolerates the procedure well. It is important to limit insufflation pressures and laparoscopy time. ⋯ Its primary use is diagnostic in penetrating and blunt trauma and in the obscure abdomen. It has been successfully employed therapeutically for acalculous cholecystitis, abscess drainage, and correction of placement of gastrostomy tubes and peritoneal dialysis catheters. It helps avoid risky transport trips and negative or nontherapeutic laparotomy with its known associated risks.

Bedside procedures. Solutions to the pitfalls of intrahospital transport.
The technology to perform diagnostic and therapeutic procedures at the bedside continues to advance. Because of documented hazards and the expense of intrahospital transport, the bedside is becoming an appealing site for procedures that are more commonly performed in radiologic, bronchoscopic, other procedural suites, and the operating room.

Dural sinus thrombosis is a relatively rare, but potentially devastating disease. The problem occurs when there is extensive thrombosis of the intracranial dural sinuses, the outflow channels of venous blood from the brain. ⋯ Treatment of this disease usually involves anticoagulants, but with mixed results. Endovascular approaches using direct infusion of thrombolytic drugs into the occluded sinuses may result in excellent recanalization and improved patient outcomes.

ReviewIntra-arterial thrombolysis for carotid circulation ischemia.
Recanalization of acutely occluded arteries in the carotid territory, particularly the middle cerebral artery, by intra-arterial delivery of thrombolytic drugs, has advanced dramatically over the last decade. Randomized prospective studies have begun to show the potential impact of this form of intervention. Still, patient selection, therapeutic window, critical care support, and experience of the management team are clearly the determining features for the success of intra-arterial thrombolysis. The use of thrombolytic agents currently available, and research involving the next generation of these agents, open a field that shows promise for the improvement of outcomes of patients whose typical prognosis is poor.
