Scientific title
Comparison of spinal anaesthesia with 1.0 mL hyperbaric bupivacaine 0.5% and total intravenous anaesthesia for minor anorectal surgery
Acronym
Study hypothesis
Minor anorectal surgery can be performed with several anaesthesia techniques. Due to multiple irrational fears, many patients deny a spinal anaesthesia and prefer a general anaesthesia. In this study we evaluate the practicability, patients' acceptability and analgetic consumption for both anaesthesia techniques in patients undergoing minor anorectal surgery.
Ethics approval
Ethics approval received from the local medical ethics committee (Medizinische Ethikkommission II Anschrift: Medizinische Ethik-Kommission II) on the 24th May 2007 (ref: 2007-085N-MA).

Condition
Minor anorectal surgery
Intervention
Patients with anorectal surgery are 1:1 randomised to either a spinal anaesthesia or a general anaesthesia. All patients received either:
1. A spinal anaesthesia with 1.0 mL hyperbaric bupivacaine 0.5% or
2. A total intravenous anaesthesia with:
2.1. 0.2 mg fentanyl and 2 mg propofol 1% per kg body weight for induction
2.2. Propofol 1% in a perfusion pump for the duration of anaesthesia, dosage depending on the demands of the patient
2.3. A laryngeal mask (size depending on the body weight of the patient)
