Analysis of intubations. Before and after establishment of a rapid sequence intubation protocol for air medical use.

INTRODUCTION: After finding the success rate of intubations in our air medical program to be less than optimal (with a success rate of only 73%), a protocol for increased doses of sedatives and neuromuscular blocking (NMB) agents was developed for field use by flight nurses and paramedics. METHODS: A retrospective chart review was performed for 100 intubations before and 100 intubations after establishment of this protocol. RESULTS: Success rate of intubation increased from 73% to 96%, which was statistically significant (p < 0.01). No difference existed between the two groups with regard to age, gender, Glasgow Coma Scale scores, nature of injury, route of intubation, number of attempts or percent intubated. Two patients (2%) became bradycardic using the new protocol. CONCLUSIONS: Our results suggest that protocols including sedatives and NMB agents can be used safely and effectively by an appropriately trained air medical team of nurses and paramedics and may improve patient care.

The likelihood of injuries when children fall out of bed.

Between 1980 and 1985, 76 children from birth to 16 years of age were reported to have fallen out of a bed, crib, or chair while in our hospital; 75% of the incidents occurred in children from birth to 5 years of age. The height of falls ranged from 1 to 3 ft. Most of the injuries were minor (scalp hematoma and facial lacerations). Our data indicate that severe head, neck, spine, and extremity injuries are extremely rare when children fall out of hospital beds. Child abuse should be suspected and ruled out when a child is seen with severe injury from a reported "fall at home."

Ultrasonography in the management of developmental dysplasia of the hip (DDH).

Real time ultrasonography, according to the method of Graf, was performed on 113 infant hips because of abnormal physical findings (ranging from hip clicks to frank dislocation). Three parameters were measured on the standard coronal images: alpha and beta angles of Graf and the d/D ratio of Morin. Results indicated that the presence of hip clicks (88 hips) in general is a benign condition and not associated with abnormal anatomy. Hips that were reduced at birth but dislocatable (Barlow hip) showed no significantly abnormal acetabular anatomy. Hips that were dislocated at rest but were reducible (Ortolani hip) showed definite abnormal acetabular anatomy and femoral head coverage. Ultrasonography is beneficial in the management of developmental dysplasia of the hip (DDH); it confirms the clinical findings and eliminates radiation exposure to the infant's pelvis, especially in the first 4-6 months of life when standard radiography is not always reliable in diagnosing DDH.

Surgical treatment of clubfoot: a comparison of two techniques.

Between 1977 and 1989, 28 clubfeet were operated on, with follow-up ranging from 2 to 13 1/2 years and averaging 79 months. Group I (16 feet; average follow-up 104 months) underwent a modified Turco's posteromedial release. The functional result in this group was satisfactory in general, but approximately one third of this group required a secondary procedure for persistent intoeing or residual metatarsus adductus. Group II (12 feet; average follow-up 45 months) underwent a modified, complete subtalar release of McKay and Simons utilizing the Cincinnati incision. No patient in this second group required a secondary procedure. In our experience, the more complete subtalar release procedure of McKay and Simons resulted in better correction than the Turco posteromedial release. Although follow-up in group II was much shorter than that in group I, we felt that 2 years of minimum follow-up in group II was meaningful, since most of the recurrence or residual deformities were noticed within 18 months after surgery. The Cincinnati incision allowed better exposure and a more complete release. Skin flap necrosis was not a problem in this series.

Injuries of the forefoot.

Dislocations and fracture-dislocations of the tarsometatarsal joints, fractures of the base of the fifth metatarsal bone, fractures of the shafts and necks of the metatarsal bones, dislocations of the metatarsophalangeal joints, fractures of the phalanges and dislocations of the interphalangeal joints each have a specific mechanism of injury, characteristic diagnostic feature, and requirement for treatment. Only by an accurate diagnosis established by careful physical and roentgenographic examination can complications be avoided.
