摘要:

A single intraportal injection of 6-OH-DA (50 mg/kg) in rats results in a functional hepatic sympathectomy 6 days following the injection. Laparotomy and mild abdominal exploration under pentobarbital anesthesia resulted in elevated plasma glucose levels within 15 minutes as a result of activation of the sympathetic nerves to the liver and adrenal gland discharge. The hyperglycemic response to trauma was reduced by fasting. The hyperglycemic response was examined in untreated rats, 6-OH-DA pretreated rats, bilaterally adrenalectomized rats, and a group which had received 6-OH-DA pretreatment as well as bilateral adrenalectomy. In nonfasted rats the presence of intact sympathetic nerves or intact adrenals was sufficient to produce the hyperglycemia. To prevent the response both nerves and adrenals must be deactivated. The hepatic nerves are primarily responsible for the early hyperglycemic response to trauma in fasted rats while in fed animals the adrenals and hepatic nerves play a more equal role.

摘要:

Recent experience with two cases of renal trauma led us to review 57 admissions to Children's Memorial Hospital. Chicago, during the last 15 years. It became apparent that a clearly defined approach to the management of renal trauma was lacking. A uniform investigation of such patients to include early intravenous pyelography and followed by renal scan or arteriography when pyelography is inconclusive in assessing the exact nature of the renal damage is recommended. The importance of these studies in diagnosing associated congenital anomalies and solitary kidney is also shown. Criteria for management by early surgical intervention or conservative approach are presented. The ultimate aim in management is to preserve the greatest possible amount of functioning renal tissue with the least risk and morbidity to the patient.

摘要:

The possibility of altered mitochondrial function consequent to burn injury was investigated. Mitochondria isolated from liver or skeletal muscle of burn-injured rats (20% tbs) were compared at 3 days postburn to shams and normal controls. Mitochondrial yields were the same for all groups. ADP:O ratios were in the theoretical ranges expected and did not differ among burn, sham, and normal animals. Respiratory control ratios (RCR's) were decreased in liver mitochondria. averaging 71.7% of normal for burned animals compared to 95.8% for the sham group. The loss of respiratory control in liver mitochondria implies inefficient use of substrate chemical energy and could contribute to postburn hypermetabolism. The different response of muscle mitochondria as compared to liver suggests that alterations may be organ specific.

摘要:

Radiolabeled fibrinogen, impedance phlebography, and venogram surveillance were carried out in ten consecutive acute spinal cord paralysis patients. Nine patients had evidence of deep venous thrombosis by radiolabeled fibrinogen technique. Venogram confirmed the presence of venous thrombosis in seven. Impedance phlebography was positive in only four. Eight patients developed a positive radiolabeled fibrinogen test after a surgical procedure. One patient with extensive venous thrombosis had multiple pulmonary emboli.

摘要:

An Emergency Medical Services (EMS) system with the capabilities of rapid response, patient extrication, basic life support, advanced life support, radio communication, and transportation provides appropriate care for a wide spectrum of injured and acutely ill patients. The validity of the selective dual response system is demonstrated by: 1) rapid provision of basic life support, 2) appropriate availability of advanced life support, 3) conservation of educational and fiscal resources, and 4) the enhancement of knowledge and manipulative skill expertise of relatively few, but busy. EMT-paramedics who are provided close medical supervision and support.

摘要:

A series of 1,187 nasotracheal intubations, carried out from January 1973 to December, 1975, used a new tube. The design included a smooth tip. a cuff with a large area of contact, low pressure and a high residual volume, and a radiopaque line which is easily visible on chest X-ray. A secondary irrigating lumen opening distal to the cuff provides closed-system irrigation, measurement of airway pressures, and sampling of tracheal gases. In the S11 intubated nontracheostomized patients who survived, the overall incidence of significant laryngeal damage was 1%. In patients intubated in excess of 10 days the damage incidence was 10%. and we suggest that tracheostomy should be carried out at this time. No patients suffered from any known permanent laryngeal damage.

摘要:

The course of three patients apparently struck by lightning is reviewed. The circumstances of the injury and the power of the lightning discharge are uncontrollable variables affecting morbidity and mortality. Immediate cardiopulmonary resuscitation followed by careful clinical monitoring and aggressive treatment of involved organ systems will help most patients to complete recovery.
