Spinal Analgesia in Operative Obstetrics*

LOW SPINAL ANAESTHESIA IN OBSTETRICS A Review of 2,475 Cases

“…in both systolic and diastolic pressures was fairly common, though in many cases the blood pressure remained unchanged. Parmley and Adriani (1946) found a slight fall in 50 per cent of their patients and a more severe but temporary fall in 50 per cent while Thorne (1952) found a blood pressure fall in 6-25 per cent of his cases. Any risk of hypotension should, of course, be avoided in anaemic or shocked patients.…”

“…Resnick (1945) reported on 257 cases of low spinal anaesthesia for vaginal delivery, and Rawlings (1950) on a further 51 1 cases with no anaesthetic deaths and no serious complications. Anderson (1946) and Thorne (1952) have also recorded series of cases with excellent results. In the American literature Parmley and Adriani (1946) described a series of 136 cases with no complications.…”
