Propofol is commonly used and well tolerated for induction of general anesthesia and is also used as a sedative in the intensive care unit. However, in rare cases, the agent may cause a fatal condition known as propofol infusion syndrome (PRIS). ⋯ Because patients typically exhibit other potentially fatal comorbidities, PRIS is always a diagnosis of exclusion. The true incidence of PRIS remains unknown, and more objective criteria for its diagnosis need to be established.

Midline minimally invasive placement of spinal cord stimulators: a technical note.
Spinal cord stimulators (SCSs) have conventionally been implanted through open approaches requiring extensive muscle dissection to perform laminectomies and permanently place the paddle lead. This approach could contribute to worsening the pain syndrome in patients who experience chronic pain. In an attempt to reduce operative times, minimize blood loss and postoperative pain, and ease the technical challenges of placing the paddle lead in the midline via a paramedian and off-midline incision, we designed a new minimally invasive surgery (MIS) technique to place the paddle lead using a tubular retractor system through a true midline approach. ⋯ Our technique is safe and effective and carries minimal surgical morbidity compared to standard open techniques for placement of SCSs.

Analgesic efficacy and technique of ultrasound-guided suprascapular nerve catheters after shoulder arthroscopy.
Conventional approaches to brachial plexus blocks may not cover the suprascapular nerve. Accordingly, after shoulder arthroscopy, sensation from the posterior part of the shoulder is commonly spared. Most previous research involving suprascapular nerve blocks described single-injection techniques. However, with the widespread availability and fairly reasonable cost of disposable infusion pumps, continuous catheter techniques provide a more appealing method of prolonging postoperative analgesia. ⋯ Continuous suprascapular catheter techniques provide good pain relief and improve postoperative analgesia after shoulder arthroscopy.

Minimally invasive versus open transforaminal lumbar interbody fusion for degenerative spondylolisthesis grades 1-2: patient-reported clinical outcomes and cost-utility analysis.
Transforaminal lumbar interbody fusion (TLIF) is the standard surgical treatment for patients with lumbar degenerative spondylolisthesis who do not respond to a 6-week course of conservative therapy. A number of morbidities are associated with the conventional open-TLIF method, so minimally invasive surgery (MIS) techniques for TLIF (MIS-TLIF) have been introduced to reduce the trauma to paraspinal muscles and hasten postoperative recovery. Because providing cost-effective medical treatment is a core initiative of healthcare reforms, a comparison of open-TLIF and MIS-TLIF must include a cost-utility analysis in addition to an analysis of clinical effectiveness. ⋯ MIS-TLIF is a more cost-effective treatment than open-TLIF for patients with degenerative spondylolisthesis and is equally effective as the conventional open-TLIF procedure, although further financial analysis-including an analysis of indirect costs-is needed to better understand the full benefit of MIS-TLIF.
