The issue of informed consent at it relates to neurosurgical professional malpractice liability and litigation has been of concern for 20 years or more. The problem persists, and the subject has been addressed by providing patient education with full disclosure regarding neurosurgical procedures. In the process of imparting informed consent, the authors studied the effectiveness of specific neurosurgical health care teaching. One hundred six persons undergoing anterior cervical fusion or lumbar laminectomy were instructed by a neurosurgeon and clinical nurse specialist with a master's degree in neurosurgery. Written testing was performed in each case immediately after a formal teaching session before surgery. Questions were simple and covered only four general topics: 1) diagnosis and surgical techniques; 2) operative risks; 3) postoperative care; and 4) goals and benefits relating to surgery. The mean score on testing immediate retention of information revealed a 43.5% overall performance rate. When patients were tested approximately 6 weeks later, the score dropped to 38.4%. This was statistically significant (chi 2, P less than 0.05). The authors encourage the concept of patient education. The data in the current study, however, suggest that the reasonable and prudent neurosurgeon making a concerted effort at patient education, with the assistance of a professional educator, cannot necessarily expect accurate patient or family recall or comprehension. Fulfillment of the doctrine of informed consent by neurosurgeons may very well be mythical.
The treatment of spasticity in severely paralyzed patients undergoing rehabilitation constitutes a significant neurosurgical challenge that requires comprehensive management. In this study, 118 patients were treated with invasive modalities when medical therapy failed. The results of percutaneous radiofrequency foraminal rhizotomy were initially successful in 95% of the 77 patients who underwent this procedure; the rate of minor complications was 5%. This procedure was satisfactorily supplemented with percutaneous radiofrequency sciatic neurectomy in 32 of these 77 patients. Four myelotomies were performed with complete success and no major complications in patients in whom percutaneous techniques had proven inadequate. In 35 instances of focal spasticity and incomplete paralysis, intramuscular neurolysis by phenol injection was used. The success rate was 89%. In 9 patients with persistent recurrent spasticity of the lower limb, open tenotomies and peripheral neurectomies were done. Success was complete and without complications. Multiple modalities must be available for the comprehensive management of patients with paralytic spasticity. (Neurosurgery 26:300-306, 1990)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
