Acronym
Study hypothesis

Condition
Analgesia and anaesthesia in orthopaedic surgery
Intervention
The 90 patients will be randomised into 3 groups. The first group will be given 2.5 ml of heavy bupivacaine 0.5% with 25 mcg of fentanyl intrathecally, the second group will be given 2.5 ml of heavy bupivacaine 0.5% with 50 mcg of morphine intrathecally and the last group will be given 2.5 ml of heavy bupivacaine 0.5% with 100 mcg of morphine intrathecally.
To minimise operator factors, there will be one anaesthetist performing the anaesthesia. Intraoperatively, patients will be given 1 g paracetamol (intravenous).
The usage of vasopressors and fluids intraoperatively will be noted. Patients are observed postoperatively in high care and the usage of patient controlled analgesia (PCA) morphine as well as respiratory rates and other side effects will be monitored closely. Patients are only given paracetamol (intravenous) 1 g four times a day (qds) in the first 24 hours as well as the morphine PCA.
