摘要:

Resuscitation of the newborn frequently requires rapid expansion of the circulating volume and correction of metabolic acidosis and hypoglycemia. Solutions commonly used for resuscitation contain various concentrations of NaHCO3, glucose, electrolytes, and albumin. We have demonstrated the wide range of osmolalities of solutions frequently available in nurseries and delivery rooms and the resultant osmolalities caused by the addition of NaHCO3. We have also shown the in vitro concentration of albumin needed to equal full-term cord blood colloid osmotic pressure (COP).

摘要:

Neonatal Intensive Care Units (NICUs) are complex environments in which caregivers from different disciplines work together under continuous stress.1,2Nurses, social workers, house officers, and attending neonatologists are forced to develop sensitivity to and awareness of one another's problems if optimal patient care is to be achieved. However, there is little systematic information available in the current literature about how any one group within the neonatal team perceives its stresses and develops coping strategies for remaining productive within the NICU.3,4The purpose of this report is to describe stresses experienced and coping strategies utilized by staff nurses in an academic NICU. Furthermore, we wish to report ways in which the information obtained in the investigation has been utilized to improve the environment of the NICU.

摘要:

A syndrome of late developing hydrothorax and hydromediastinum after central vein catheterization is presented. Use of inflexible catheters in sharply curved intrathoracic veins is proposed as a mechanism for the development of late hydrothorax and hydromediastinum. The authors recommend that physicians avoid the use of a large inflexible central venous catheter when not essential to the patient's management. The right jugular venous approach is recommended when inflexible catheters need to be used.

摘要:

The free tetraiodothyronine index (FT4I) and free triiodothyronine index (FT3I) in burn patients represented the serum levels of free (dialyzable) T4and free T3, respectively. FT4I and FT3I were lower with greater burn size and were lower in nonsurvivors than expected for the burn size. There was no compensatory elevation of basal or releasing hormone-stimulated thyrotrophin (TSH) concentrations. Reverse T3was higher with greater burn size. T3treatment restored FT3I but did not affect mortality or resting metabolic rate (MR) measured in survivors, compared with placebo therapy. Whereas the hypermetabolic response to burn injury appeared to be independent of thyroid hormones, MR was correlated positively with burn size and with elevated plasma nor-epinephrine and epinephrine concentrations for several weeks after injury. Lack of augmented TSH concentrations, absence of low plasma reverse T3, and presence of hypermetabolism suggest that the reduced plasma free T3does not indicate functional hypothyroidism, but may represent an adaptation to the assumption of metabolic control by the sympathetic nervous system.

摘要:

Helium detectors utilizing thermal conductivity are sensitive to the presence of nitrous oxide (N2O) and oxygen (O2). Measurement of the level of these gases within the spirometer may be used to obtain the true helium concentration for use in the calculation of functional residual capacity (FRC). Linear relationships were obtained relating the change (Δ) in reading of the helium meter by nitrous oxide and oxygen. The regression equations are:ΔO2= 0.027 (%O2) – 0.513ΔN2O = –0.276 (%N2O)Failure to correct the helium reading for N2O will overestimate lung volume; elevations of O2above 21% will underestimate the lung volume.

摘要:

Fenestrated tracheostomy tubes allow the patient to use the upper airway and, in addition, facilitate assistance with bronchial hygiene. The precut fenestrations in disposable tracheostomy tubes are not always appropriately aligned in all patients. A bedside technique to modify the position of the fenestration in disposable fenestrated tracheostomy tubes is described.

摘要:

Tracheal intubation is now regarded as an integral part of modern anesthetic management, respiratory care of the critically ill and resuscitation. However, anesthesiologists occasionally encounter difficulty in intubating the trachea due to various anatomical abnormalities. Various techniques have been described to accomplish tracheal intubation including fiberoptic bronchoscopy and cricothyroidotomy.1,2One of the alternate techniques described is to thread the endotracheal tube over a malleable introducer which has been introduced into the trachea.3We present our experience of intubating the trachea in difficult cases utilizing a recently introduced intubation guide.
