Anesthesia for selected procedures.

This article reviews selected procedures for which a particularly close working relationship between the surgeon and the anesthesiologist is essential for patient safety. Anesthetic considerations for upper and lower gastrointestinal endoscopies, bronchoscopy for aspirated foreign bodies, resection of mediastinal masses, thoracotomies for procedures requiring one-lung anesthesia, and surgery for burn patients are reviewed.

Anesthesia

Anesthesia outside the operating room.

Many new diagnostic and surgical procedures rely on immobile equipment such as computed tomography or magnetic resonance scanners, biplanar fluoroscopes, or radiotherapy units. To facilitate these procedures in infants and children, anesthesiologists must provide services in a variety of unique environments. This article reviews the anesthetic equipment and techniques that have been adapted to provide anesthesia for children outside the operating room.

Anesthesia

Increased sensitivity of the isometric contraction of the neonatal isolated rat atria to halothane, isoflurane, and enflurane.

Isolated atria from neonatal (0-5 day old) and adult (50 +/- 5 day old) rats were perifused in oxygenated Kreb's Henseleit solution at 30 +/- 0.5 degrees C and exposed to four different concentrations of halothane, isoflurane, or enflurane while isometric contractile tension was recorded and compared with control atria. ED50 values (mM of anesthetic required to produce 50% reduction in contractile tension) of neonates for halothane (0.18 +/- 0.01), isoflurane (0.41 +/- 0.05), and enflurane (0.41 +/- 0.04) were significantly lower than those of adults (0.35 +/- 0.02, 0.80 +/- 0.05, and 1.15 +/- 0.05, respectively). Furthermore, neonatal ED50 calculated as per cent of adult ED50 was significantly less for enflurane (35%) than for halothane (54%) or isoflurane (51%).
