Liver cirrhosis, a devastating liver fibrosis caused by hepatitis/inflammation or tumors, is a major comorbid factor in known surgery fields, such as cardiovascular and abdominal surgeries. It is important to review possible comorbid results in neurosurgical procedures in cirrhotic patients. In the reviewed literature, Child-Pugh and model for end-stage liver disease scores are commonly used in the assessment of surgical risks for cirrhotic patients undergoing abdominal, cardiovascular or neurosurgical procedures. The major categories of neurosurgery are traumatic brain injury (TBI), spontaneous intracranial hemorrhage (SICH), brain tumors, and spinal instrumentation procedures. TBI was reported with surgical mortality as high as 34.5% and a complication rate of 87.2%. For SICH, mortality ranged from 22.7% to 47.0%, while complications were reported to be 43.2%. Less is discussed in brain tumor patients; still the postoperative hemorrhage rate approached 26.7%. In spinal fusion instrumentation procedures, the complication rate was as high as 41.0%. Preoperative assessment and correction could possibly decrease complications such as hemorrhage, wound infection and other cirrhosis-related complications (renal, pulmonary, ascites and encephalopathy). In this study, we reviewed the neurosurgical-related literature with regard to liver cirrhosis as a prognostic factor influencing neurosurgical outcomes.

This paper reviews the safety data on bromocriptine administration for 1 to 10 years at daily doses of 1.25 to 80 mg in over 1100 patients with pituitary hormone overproduction (mainly from prolactinomas and growth-hormone producing adenomas), at daily doses of 3.75 to 170 mg in over 700 patients with Parkinson's disease, and at daily doses of 2.5 to 20 mg in 28 patients with various other conditions. In addition, information is provided on the safety for mother and child of bromocriptine administered at daily doses of 2.5 to 35 mg throughout gestation (54 pregnancies) or during its later stages (39 pregnancies). The side-effects of long-term bromocriptine treatment are usually no different from those seen during short-term treatment; most of them are relatively benign, and they have been shown in virtually all patients to be reversible. Bromocriptine appears to have no harmful effect on hepatic, renal, haematologic, or cardiac functions. It is considered that a hitherto unknown, severe though rare side-effect of bromocriptine is unlikely to be reported after such long experience.

We have treated 102 Parkinson patients with bromocriptine for up to 6 years; most of these posed problems of management when referred to us. Forty-two continue to take bromocriptine, at a mean dose of 49 mg daily (range 10-160), in combination with some 50% of their previous optimal dose of levodopa (with or without a decarboxylase inhibitor). We consider the main indications for bromocriptine are severe dyskinesia, early morning dystonia, and "wearing off" reactions. Contraindications include hallucinations, delusions, substantial confusion, acute myocardial infarction, active peptic ulceration, and active pleuropulmonary disease.
