RESUMEN
Systemic donor infections especially with gram-negative organisms are regarded as an absolute contraindication to cadaveric organ donation for transplantation. This is largely due to fear of transmitting the pathogenic organisms to the immunosuppressed recipient. However, due to the current shortage of organs available for transplantation, clinicians are faced with the option to use organs from infected donors. Between 1996 to January 2006, we collected 44 solid organs. Two out of nine donors had microorganisms from blood cultured. Case 1 was of 23-year old woman whose cause of brain death was intracerebral bleeding due to a traffic accident. The donor had stayed 9 days in the intensive care unit prior to brain death. Two kidneys, two livers (split), and or heart were used. Klebsiella was the organism on blood culture. Case 2 was of 35-year-old man; cause of brain death was cerebral hematoma due to traffic accident. The donor had stayed 6 days prior to brain death onset. The liver and two kidneys were used. Acinetobacter baumannii was yielded upon blood culture. All donors were treated with appropriate antibiotics for at least 48 hours prior to organ procurement with consequent negative blood cultures, while the recipients received the same culture-specific antibiotics for 10 days following transplantation. One donor (case 1) heart and both donor corneas were not used due to infection. All patients are alive with excellent graft function at a median of 90 days following transplantation. In conclusion, our results suggested that bacteremic donors with severe sepsis under proper treatment can be considered for transplantation.

BACKGROUND: Thromboangiitis obliterans (TAO) is a non-arteriosclerotic segmental inflammatory occlusive vasculitis typically in the upper and lower extremities affecting small- and medium-sized arteries and veins. We present the treatment protocol for TAO involving the use of peripheral sympathetic block through an axillary catheter. CASE REPORT: An unconscious 56-year-old female patient was transferred to the emergency service, intubated, and mechanically ventilated. The patient was provisionally diagnosed with hypertensive intracranial hematoma and admitted to the intensive care unit. Invasive arterial pressure monitoring was performed through the left radial artery cannula. Four days later, upon the observation of symptoms of a circulatory disorder in the fingers distal of the left and right hands, the cannula was removed from the left radial artery, and another was placed in the left dorsalis pedis artery. At the same time, an 18 Gauge catheter was placed in the axillary perineural sheath bilaterally, and a total of 10 ml lidocaine 0.5 % (5 ml for each side) was injected six times a day. During each injection, the temperature was measured using a surface probe on the distal of the fingers with poor perfusion and another area of the same hand with good perfusion. Lidocaine treatment protocol through the axillary perineural catheter was applied for 15 days for the right hand and 18 days for the left hand. As the treatment proceeded, a significant increase was observed in the results of the temperature measurements on the fingers with poor perfusion. Conclusion: We believe that a peripheral sympathetic block as we report herein could be considered as an alternative in the treatment of TAO. HIPPOKRATIA 2018, 22(3): 141-144.
RESUMEN
Women with underlying rheumatic heart disease, even if well compensated, can easily be affected by acute heart failure caused by out-of-the-ordinary cardiorespiratory requirements during pregnancy. In such cases, medical therapy is not always sufficient to drive a heart, and open heart operation might be necessary. Many factors associated with cardiac operations requiring cardiopulmonary bypass, such as hypothermia, can adversely affect both the mother and the fetus, but the morbidity and mortality rates are higher for the fetus than the mother. Because fetal heart tones were lost during cardiopulmonary bypass and were reheard in the intensive care unit in our case presentation, we have presumed that the loss of fetal heart tones should not always indicate fetal death and have discussed harmful factors in relation with the fetal morbidity and mortality in light of the literature.

Pulmonary microvascular injury has become a recently studied phenomenon that may be responsible for most of the complications associated with the lungs. Thirty patients undergoing partial hemilaminectomy or discectomy due to hernia of nucleus pulposus underwent Tc-99m HMPAO lung clearance as well as Tc-99m pertechnetate lung scintigraphy pre-operatively, and following general anaesthesia with halothane and isoflurane (third, fourth and tenth post-operative days). The results were compared with conventional techniques and haemodynamic parameters during the peri-operative period. In order to demonstrate acute phase changes under general anaesthesia and to perform pathological examinations, 21 New Zealand rabbits underwent radionuclide studies with Tc-99m HMPAO or Tc-99m pertechnetate. Lung biopsies were also performed. Despite no significant differences in any of the conventional diagnostic techniques, Tc-99m pertechnetate lung scintigraphy was performed for both the halothane and isoflurane groups, and Tc-99m HMPAO lung clearance was performed for the isoflurane group pre- or post-operatively. Tc-99m HMPAO lung clearance was impaired significantly in the halothane group on the third post-operative day (half time: 6.4 +/- 1.6 pre-operative and 13.76 +/- 3.3 s, P < 0.001) decreasing to pre-operative levels on the tenth post-operative day. Acute phase exposure to halothane was characterized with extremely abnormal Tc-99m HMPAO lung clearance in rabbits with respect to isoflurane, diminishing to control levels on the third day (half time: 8.7 +/- 86 control and 28.65 +/- 4.6, P < 0.001). Pathological examinations also demonstrated endothelial damage on acute exposure in the halothane group. General anaesthesia with halothane may give rise to alveolar microvascular injury, which generally seems to be underdiagnosed and may lead to serious post-operative complications.

Stellate ganglion block is a selective sympathetic block that affects the ipsilateral head, neck, upper extremity and upper part of the thorax. Convulsions are a recognized complication of intra-arterial injection during stellate ganglion block. As central nervous system toxicity depends ultimately on the concentration of the local anaesthetics presented to the brain, the likely causative factors are discussed as well as the types of toxic symptoms and their onset times. The paper considers the aetiological factors of such convulsions resulting from stellate ganglion block in two patients.
