Randomized Controlled Trial Clinical Trial
Recollection of dreams after short general anaesthesia: influence on patient anxiety and satisfaction.
We ascertained whether dreams during short general anaesthesia influence subsequent patient satisfaction and anxiety. ⋯ Dreaming during general anaesthesia is common but does not influence satisfaction or anxiety after anaesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Intrathecal fentanyl added to intrathecal bupivacaine for day case surgery: a randomized study.
The implication of intrathecal lidocaine in neurological toxicity has made intrathecal bupivacaine the commonly used drug for local anaesthesia in ambulatory surgery. However, in high doses intrathecal bupivacaine may produce a high level of sensory and motor block, and arterial hypotension; discharge from hospital may be delayed. Intrathecal opioids added to low-dose local anaesthetics produce a synergistic effect without increasing the sympathetic block or delaying discharge. The aim of our study was to identify the minimum effective dose of intrathecal fentanyl that in combination with low-dose intrathecal bupivacaine would provide adequate surgical conditions without prolonging recovery. ⋯ Fentanyl 12.5 microg added to low-dose bupivacaine (5 mg) intrathecally provides better surgical anaesthesia and increased reliability of block than intrathecal fentanyl 7.5 or 10 microg. Haemodynamic stability was the same for all dose combinations used.
