The review focuses on six papers published in 2004 that pertain to operating room (OR) efficiency. ⋯ Interventions studied included changing when OR time was released, reducing surgical times, reducing turnover times, reducing OR times with block rooms, and improving prediction of case duration. The incremental improvements in OR efficiency and reductions in labor costs were small as compared with allocating OR time and scheduling cases appropriately.

Objectives To retrospectively analyze by indices of success, patients with chronic complex pain, including, axial low back pain, receiving dual spinal cord stimulation (SCS) systems. Methods Eighteen patients with dual spinal cord stimulators have been retrospectively and nonrandomly analyzed. The preponderance of patients in our study group had failed back surgery syndrome (FBSS). ⋯ Thirteen (81%) patients with dual lead SCS therapy were willing to repeat the SCS implant procedure. Complications occurred in 43.7%. Conclusions Dual spinal cord stimulation is appropriate and efficacious for treating complex pathology and complex pain that including pain of the low, axial back.

To study the application of navigated stereoscopic display of preoperative three-dimensional (3-D) magnetic resonance angiography and intraoperative 3-D ultrasound angiography in a clinical setting. ⋯ Stereoscopic visualization enhances the surgeon's perception of the vascular architecture, and integrated with navigation technology, this offers a reliable system for identification and clipping of AVM feeders in the initial phase of the operation.

To investigate the possible advantage of administration of preemptive oral ibuprofen in children after ambulatory pediatric urologic surgery such as penile surgery (circumcision and hypospadias repair) and inguinal surgery (communicating hydrocele and orchidopexy), a study was performed on the experience of postoperative pain, nausea or vomiting, and resumption of normal activities such as normal sleep and play activity. In addition, this study has validated a method of measurement of pain and resumption of normal activities in children. ⋯ Children who received preoperative oral ibuprofen (10 mg/kg) did not experience less pain or less nausea and vomiting, and did not show a better pattern of sleep and play up to 2 days after ambulatory pediatric urologic surgery than children who did not receive this medication.

In this study, we attempted to improve the delineation of the infiltration zone in gliomas using proton magnetic resonance spectroscopic imaging (1H MRSI). In conventional magnetic resonance imaging (MRI), the boundaries of gliomas sometimes are underestimated. 1H MRSI is a noninvasive tool that can be used to investigate the spatial distribution of metabolic changes in brain lesions. The purpose was to correlate tumor cell density from histopathological specimens with metabolic levels and the coregistered metabolic maps. ⋯ Our preliminary data suggest that 1H MRSI may be useful in combination with frameless stereotaxy to define more exactly the tumor infiltration zone in glioma surgery compared with conventional anatomic MRI alone.
