Lung imaging characteristics in a patient infected with Elizabethkingia miricola following cerebral hemorrhage surgery: A case report

BACKGROUND Elizabethkingia miricola is a non-fermenting gram-negative bacterium,which was first isolated from the condensate of the Russian peace space station in 2003.Most studies on this bacterium have been carried out in the laboratory,and clinical case studies are rare.To date,a total of 6 clinical cases have been reported worldwide.CASE SUMMARY We present the first case of postoperative pulmonary infection in a patient with intracerebral hemorrhage due to Elizabethkingia miricola.The imaging character-istics of pulmonary infection were identified and the formulation and selection of the clinical treatment plan for this patient are discussed.CONCLUSION Elizabethkingia miricola infection is rare.When pulmonary infection occurs,computed tomography imaging may show diffuse distribution of a ground glass density shadow in both lungs,the air containing bronchial sign in local areas,thickening of bronchial vascular bundle,and pleural effusion.

Monitoring cerebral ischemia during cerebrovascular surgery

Patients undergoing intracranial cerebrovascular surgery under general anesthesia are at risk of cerebral ischemia due to the nature of the surgery and/or the underlying cerebrovascular occlusive disease.It is thus imperative to reliably and continuously monitor cerebral perfusion during this type of surgery to timely reverse ischemic processes.The aim of this review is to discuss the techniques currently available for monitoring cerebral ischemia during cerebrovascular surgery with a focus on the advantages and disadvantages of each technique.

Clinical Observation of Double Tube Laryngeal Mask in Fast-Track Anesthesia for Limb Orthopedic Surgery in Children with Cerebral Palsy

Objective: To compare and analyze the effect and safety of double tube laryngeal mask and endotracheal intubation general anesthesia in fast track anesthesia for limb orthopaedic surgery in children with cerebral palsy. Methods: 78 children with cerebral palsy undergoing limb orthopedic surgery were randomly divided into laryngeal mask group and intubation group, with 39 cases in each group. The perioperative hemodynamic indexes, anesthesia effect related indexes, anesthesia related complications or adverse reaction rates of the two groups were observed and compared between the two groups. Results: When the two groups of children entered the room, there was no significant difference in MAP and HR (P > 0.05);MAP and HR of children in the intubation group were higher than those in the laryngeal mask anesthesia group (P Conclusion: Laryngeal mask is used to establish the airway of intravenous general anesthesia in limb orthopaedic surgery of children with cerebral palsy, which is conducive to the stability of children’s circulatory and respiratory system, to reduce the impact of narcotic drugs on children, to reduce the incidence of postoperative anesthesia related complications, and to improve the anesthetic effect. It meets the requirements of fast track anesthesia, and can be widely used in clinical practice.

Clinical application of retrograde cerebral perfusion for brain protection during the surgery of ascending aortic aneurysm:50 cases report

Objective To assess retrospectively the effects of different protective methods on brain in ascending aortic aneurysm surgery. Methods In 65 patients, aneurysm was dissected to the aortic arch or right arch. To protect brain, deep hypotermic circulatory arrest ( DHCA.) combined with retrograde cerebral perfusion ( RCP) June 2003 Vol11 No2 through the superior vena cava ( n = 50) and simple DHCA ( n = 15) were used during the procedure. Blood samples for lactic acid level from the jugular vein were compared in both groups at different plase, and perfusion blood distribution and oxygen content difference between the perfused and returned blood were measured in some RCP patients. Results The DHCA time was 35.9 ± 8 min (10. 0 - 63. 0 min) and DHCA+ RCP time was 45.5 ± 17. 2 min (16. 0 - 81. 0 min)The resuscitationtime was 7.1 ± 1.6 h (4.4 - 9.4H)in DHCA patients and 5.4±2.2h(2.0-9.0 h)in RCP patients. Operation death was 3/15 in the DHCA group and 1/50 in the RCP patients. Central nervous complication

Monitoring of antegrade selective cerebral perfusion for aortic arch surgery with transcranial Doppler ultrasonography and near-infrared spectroscopy

Objective To evaluate the safety and efficacy of antegrade selective cerebral perfusion (ASCP) during aortic arch surgery as a means of extending the safe period of systemic circulatory arrest using multimodality neuromonitoring to objectively quantify the physiologic responses Methods In twenty two patients (all less than age 60) scheduled for repair of an aortic arch aneurysm, preoperative verification of effective collateral perfusion through both the carotid and vertebrobasilar arterial systems was documented with transcranial Doppler ultrasonography (TCD) During cardiopulmonary bypass, the sole arterial inflow from the pump was via the right subclavian artery The magnitude of ASCP was quantified by TCD using peak middle cerebral artery velocity, while flow adequacy was measured by continuous regional cerebrovenous oxygen saturation (rSO 2) using dual wavelength spatially resolved near infrared spectroscopy Results All patients experienced an uneventful recovery Flow in the middle cerebral artery became undetectable at ASCP < 5?ml·kg 1 ·min 1 , so adjustments from a 15-20?ml·kg 1 ·min 1 baseline were used to maintain rSO 2 above 50% Furthermore, ASCP flow was highly correlated ( P <0 01) with both peak middle cerebral artery velocity and rSO 2 ( r =0 86 and 0 96, respectively) Conclusion Neuromonitoring guided ASCP may be expected to extend the safe period and is at least partly responsible for the absence of neurologic complications in this patient cohort
