The aim of this study was to evaluate the results of conservative and surgical management options for traumatic cerebrospinal fluid (CSF) leakage complicating skull base fractures. The subjects were 81 patients who were treated between 1996 and 2003 for CSF leaks that had persisted for 24 h or longer after head injury. For each case the medical records were reviewed, and the data collected were as follows: demographic features, clinical and radiological findings, management options, complications and outcome scores. Analysis was done with patients grouped according to Glasgow coma scale (GCS) score at admission (8), and findings for three treatment methods (conservative, CSF drainage, surgery) were evaluated. In 32 cases (39.5%), the CSF leakage resolved spontaneously, and the mean hospital stay for these patients was 14+/-11 days. Twenty-four patients (29.6%) were treated by CSF drainage, and seven of these individuals ultimately required surgery to close the leak. Hospital stay was 17+/-7 days. Twenty-five patients (30.9%) underwent surgery as the initial treatment step, and the mean hospital stay for these individuals was 15+/-9 days. The large majority (74.2%) of patients with admission GCS scores 8 resolved spontaneously. The factors that had a critical influence on outcome in this series were level of consciousness on admission and presence of additional intracranial pathology associated with CSF leakage within cases of traumatic CSF fistulae due to skull base fractures. Treatment decisions should be dictated by the severity of neurological decline during the emergency period and the presence/absence of associated intracranial lesions. The timing for surgery and CSF drainage procedures must be decided with great care and with a clear strategy. The authors offer a treatment algorithm.
This is a prospective, randomized, controlled trial that compared the efficacy of different protocols of local tissue infiltration with levobupivacaine or levobupivacaine-methylprednisolone at the surgical site for pain relief after lumbar discectomy. The objective of the study was to determine the efficacy of preemptive wound infiltration with levobupivacaine and levobupivacainemethylprednisolone at the surgical site for pain relief. Patients usually suffer significant pain after lumbar discectomy. Wound infiltration with local anesthetics with or without corticosteroids is one method to address this. A total of 100 patients were randomly allocated to five equal groups as follows: Group I had the musculus multifidi near the operated level infiltrated with 30 mL 0.25% levobupivacaine and 40 mg methylprednisolone just before wound closure; Group II had the same region infiltrated with 30 mL 0.25% levobupivacaine alone before closure; Group III had this region infiltrated with 30 mL 0.25% levobupivacaine and 40 mg methylprednisolone before the incision was made; in Group IV this region was infiltrated with 30 mL 0.25% levobupivacaine alone before incision; and in Group C (controls) this region was infiltrated with 30 mL 0.9% NaCl just before wound closure. Demographics, vital signs, postoperative pain scores and morphine usage were recorded. All four treatment groups showed significantly better results than the control group for most parameters. The treated groups had lower parenteral opioid requirements after surgery, lower incidences of nausea and shorter hospital stays. Further, the data indicate that, compared with infiltration of these drugs at wound closure, preemptive injection of levobupivacaine or levobupivacaine-methylprednisolone into the muscle near the operative site provides more effective analgesia after lumbar discectomy. Our data suggest that preemptive infiltration of the wound site with levobupivacaine alone or combined with methylprednisolone provides effective pain control with reduced opiate dose after unilateral lumbar discectomy.
Cranial surgery without hair removal is safe and does not increase the risk of surgical wound infection. Patients naturally prefer to keep their full head of hair. We believe that preoperative hair removal is not necessary in preparation for any type of cranial neurosurgery.
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.
