Experiences with unselected intrapartum fetal monitoring in the 3-year period from 1972-1974 are compared with those of the 3 preceding years before monitoring was instituted. The effect of monitoring all laboring patients is correlated with a significant decrease in the perinatal mortality and a significant increase in the cesarean section rate. ⋯ The advantages and disadvantages of unselected electronic monitoring are discussed. The importance of education of medical and paramedical personnel necessary for intense intrapartum care is emphasized.

Monitoring data in 16 primates subjected to septic or hemorrhagic shock and resuscitated with various solutions is presented. From a paractical standpoint, central venous pressure and urine output appear to be the best indices to use in the emergency department for resuscitation of the shock victim. The sophisticated measurements such as cardiac output, thermodye volumes, pulmonary artery wedge pressure and oxygen consumption should be reserved for the individual with depressed cardiovascular reserves and who needs "fine tuning" of his volume status.

Patient monitoring in the operating room--an anesthetist's viewpoint.
The spectrum of patient monitoring techniques and equipment presently available in the operating room is reviewed from the anesthetist's viewpoint. Although electronic monitoring instruments are becoming more sophisticated with self-contained microprocessors or computer interfaces, few are designed for performance specifically within the hostile environment of the operating room. ⋯ Event recording during anesthesia depends upon the time-honored but inefficient handmade record of the anesthetist. Within the context of developing a computer-assisted monitoring and display system, this commentary presents the physician's perspective of instrumentation limitation and successes.

Development of a special electrode for continuous subcutaneous pH measurement in the infant scalp.
Using a combined special glass electrode it is possible to monitor pH ratios and pH variation in the subcutaneous tissue of the infant scalp continuously. Tests on a normal sample of newborn babies immediately after birth showed a significant correlation between tissue pH and capillary blood pH, with the trend of pH variation being broadly similar in both measurement media.
