Background Accidental intrathecal injection of bupivacaine during epidural analgesia in labour remains a hazard, with the potential to cause total spinal anaesthesia and maternal collapse. Sacral block appears early after intrathecal injections compa

Summary Thirty five patients presenting for elective total hip replacement were randomly allocated to receive a premedication of 60 or 90 mg controlled-release oral morphine or 15 mg intramuscular morphine. Postoperative analgesia was assessed using

We have developed a computer program that estimates venous admixture (intra-pulmonary shunt) from four measurements: haemoglobin concentration, end-tidal carbon dioxide tension (PE'CO2), fractional inspired oxygen concentration (FIO2) and pulse oxime

The fluid warming capabilities of the Bair Hugger, Hotline, Standard Ranger and Fluido devices were evaluated in the laboratory with gravity flow via a 14G cannula (1 m head of fluid) and with the fluid bag pressurised to 300 mmHg. The resulting flow

A high degree of safety from fires and explosions exists in operating theatres in the U.K. and this is reflected in the extremely low number of fatal and non-fatal accidents which occur. This has been achieved by safety precautions which in some resp

A technique is described for analysing small discrete samples of gas (about 100 μl) by injecting them into a stream of carrier gas being continuously sampled by a ‘respiratory’ mass spectrometer. This involves interrupting the normal respiratory

Anaesthesia was induced in two volunteers using 100% nitrous oxide and 92%, 87% and 80% nitrous oxide with oxygen, at atmospheric pressure; 50% nitrous oxide with oxygen at 2 atmospheres absolute (ATA); and 85% nitrous oxide with oxygen at 1.2, 1.4,

In seven neonates, whose mothers were given pethidine during labour, urine was collected for the first 24–40 h of life. Urinary volume and pH, and concentrations of pethidine and norpethidine in the urine were measured. Urine flow rate was low for

A mathematical model in the form of an Algol program for a digital computer is used to match, breath by breath, experimental studies (as described in Part I) of nitrousoxide anaesthesia in two volunteers. Initially, normal values are assumed for attr

The volume of discard for valid blood sampling from indwelling femoral (leader cath) and radial (Venflon) arterial cannulae (with internal volume of cannula plus connecting tubing of approximately 2 ml) was investigated by analysing sequential 2-ml a
