Anaesthesia

The Reverend Doctor Robert Laws (1851-1934) followed in the footsteps of David Livingstone to Central Africa. At the beginning of a long and distinguished career as a medical missionary in Christian service to the country that has since become the Republic of Malawi, he was a prime mover in the setting up of a mission station at Cape Maclear, on the shores of Lake Malawi (formerly known as Lake Nyasa and closely associated with the discoveries of Doctor Livingstone). There, on 2 March 1876, Laws used chloroform to produce surgical anaesthesia when he operated on a young African male who had a cystic tumour above his left eye.

Twenty five patients were treated with an epidural blood patch for persistent headache, following a known or suspected dural puncture. Fifteen to 20 ml blood was injected into the epidural space through a catheter inserted one space away from the dural puncture. The catheter technique was useful in confirming the clinical diagnosis of previously unrecognised dural tap in six patients with severe headache. It was possible to perform the blood patch single-handed.

Comparative Study
Bronchial intubation. A comparison between polyvinyl chloride and red rubber double lumen tubes.
Red rubber and polyvinyl chloride bronchial double lumen tubes were compared. Polyvinyl chloride tubes are easier to pass quicker to position and cause less damage to the mucosa of the respiratory tract than the red rubber equivalents.

In a prospective study of 51 young male outpatients given spinal anaesthesia through a 25-gauge needle, we found a 37.2% incidence of postdural puncture headache. In addition, 54.9% complained of backache after surgery. ⋯ These patients had a higher incidence of postoperative backache and pain during lumbar puncture. It is concluded that spinal anaesthesia is not a satisfactory technique for outpatient procedures in young men.
