目的观察不同血容量状态下颅高压的急性呼吸窘迫综合征(ARDS)猪模型,增加呼气末正压(PEEP)后,其血流动力学状态、颅内压(ICP)及脑氧分压(PtiO2)的变化。方法选取雄性14~16月龄巴马小型猪12头,随机数字表法随机分成低血容量组和正常血容量组。建立ARDS和颅高压模型。自5 cmH2O(1 cmH2O=0.098 kPa)水平逐步增加PEEP 5 cmH2O,直至25 cmH2O。采用重复测量的方差分析,并应用Sidak法进行多重比较和P值的校正。结果随着PEEP逐渐增加,正常血容量组ICP逐渐升高,而低血容量组ICP逐渐下降;当PEEP在5、10、15 cmH2O时,两组间ICP值分别为(25.83±1.47)mmHg(1 mmHg=0.133 kPa)比(27.00±1.63)mmHg、(27.33±1.75)mmHg比(27.67±2.21)mmHg、(28.83±1.72)mmHg比(27.5±2.06)mmHg,差异均无统计学意义(t=0.793、0.227、0.906,P值均>0.05);当PEEP在20、25 cmH2O时,两组间ICP值分别为(31.33±2.07)mmHg比(26.5±3.35)mmHg、(31.67±2.94)mmHg比(25.83±3.67)mmHg,差异均有统计学意义(t=3.284、3.964,P值均<0.01)。随着PEEP逐渐增加,两组PtiO2均逐渐下降,其中低血容量组下降更明显;在各PEEP水平时,两组间PtiO2值分别为(19.83±2.64)mmHg比(14.33±3.50)mmHg、(18.67±2.50)mmHg比(12.33±3.88)mmHg、(17.67±3.88)mmHg比(10.67±3.88)mmHg、(15.33±2.34)mmHg比(9.17±3.54)mmHg、(13.67±3.61)mmHg比(6.67±2.73)mmHg,差异均有统计学意义(t=2.333、3.319、3.668、3.231、3.668,P值均<0.05)。结论PEEP对血流动力学、颅内压、脑代谢作用受不同容量状态的影响。低血容量状态下,PEEP逐渐上升,其心输出量、血压和PtiO2下降更明显。 相似文献

BackgroundThe patency of cranial bypasses must be carefully evaluated during and after the microsurgical procedure. Although, several imaging techniques are used to evaluate the patency of bypasses, their findings are sometimes difficult to interpret.PurposeThe goal of this study was to assess the consistency of different diagnostic modalities for evaluating intracranial bypass patency.Patients and methodThis prospective study included 19 consecutive patients treated with EC-IC or IC-IC bypass for MoyaMoya disease (MMD) or complex/giant aneurysms between June 2016 and June 2018. In the early postoperative period (< 7 days), all patients had transcranial Doppler (TCD), CT angiography (CTA) and MRA to demonstrate patency of anastomoses and to confirm exclusion of the aneurysm. When findings of anastomosis patency differed between these techniques, conventional angiography was performed.ResultsAll anastomoses were patent on indocyanine green videoangiography at the end of microsurgical procedure. The results of noninvasive postoperative exams were consistent to demonstrate the patency of anastomoses in 13 patients. In 4 patients, a discrepancy in patency of anastomoses arose between TCD, CTA and MRI in the early postoperative period. In 2 other patients, the interpretation of bypass patency remained inconclusive before the decision to occlude the aneurysm. In these 6 patients, a significant edema was noted in 2 cases, a postoperative subdural hematoma in 1 case, a low flow in the anastomosis in 1 case and vasospasm in 2 cases. The anastomosis was patent on the conventional angiography in five patients.ConclusionNoninvasive imaging techniques provide useful data about the patency but their findings should be carefully interpreted due to local anatomical, physiological, and pathological factors. In case of discrepant findings, conventional angiography including supraselective catheterization of the donor vessel is suggested. 相似文献

Intracranial subdural hematoma is a rare, but potentially lethal complication of neuraxial procedures. Considering the high frequency of neuraxial techniques in the obstetric population, parturients are more susceptible to this fearful complication. The diagnosis is often masked and delayed because it shares similar clinical characteristics with posdural puncture headache, with headache being the most common symptom. This case report describes a timely diagnosis and successful management of an intracranial subdural hematoma, after unintentional dural puncture during labour epidural analgesia. Postpartum headache following epidural analgesia, remains a clinical challenge for the caring team, requiring a close follow-up and awareness for non-benign causes that require prompt management, avoiding devastating consequences. 相似文献

IntroductionThe recurrent laryngeal nerve (RLN) originates from the Vagus nerve intrathoracically. It passes through the tracheoesophageal groove (TEG) in the neck and different variations in this section were observed. The RLN is at highest risk for injury during the thyroid surgery. Therefore, it is important to know variations to decrease the injury effectively.Presentation of caseA 50 years-old woman with no thyroid related complaints except for enlargement of the thyroid gland in recent 12-months that annoyed her during neck movement and for aesthetic features. Medical, surgical, drugs, irradiation history, laboratory data, and physical examination was unremarkable except for multi-lobulated enlarged thyroid gland. The CT scanning study revealed intrathoracic extension of the gland. Patient underwent total thyroidectomy with suspicious diagnosis of multinodular goiter which was confirmed later by pathologic study. Intraoperative exploration of the right RLN discovered an intracranial branch originating from the recurrent laryngeal trunk just beneath the inferior thyroid artery (ITA) at the level of the nerve intersection. The branch then passed laterally about 1 cm and penetrated in ipsilateral carotid sheath.DiscussionThe RLN has different anatomical variations in either the right or the left side of the neck. However extra-laryngeal nerve branching is the most common variation but other seldom variations including the non-RLN, and intracranial branch should be mentioned by surgeon intraoperatively.ConclusionTo decrease iatrogenic injuries to RLN and its associated nerve branches knowledge of the nerve anatomy is mandatory for surgeon to prevent morbid side effects. 相似文献

Barbiturates are used clinically as anaesthetics and to reduce raised intracranial pressure. One side effect is hypotension, usually ascribed to a depression of cardiac contractility, while their effects on the resistance vessels are more controversial: both vasodilation and vasoconstriction have been described. This study analyzes the effects of thiopental on basal vascular tone in the cat skeletal muscle. We found that total resistance increased by almost 20% at low (50mol/l) and decreased down to about 50% of control at high (350 mol/l) plasma concentrations of thiopental. The vasoconstriction dominated in the large arterioles (i.d. >25 m) and the vasodilation in the small arterioles (i.d. <25 m). A dosedependent inhibition of myogenic vascular reactivity (here defined as the maximum resistance increase to a transient rise in transmural pressure) coincided with the vasodilation. Autoregulation of blood flow was depressed by thiopental. During vasoconstriction there was a net transcapillary fluid absorption and during vasodilation a net fluid filtration. The fluid movements could be ascribed to variations in capillary hydrostatic pressure. If applicable to the cerebral circulation these results suggest that thiopental at high plasma concentrations might induce, instead of reduce, interstitial brain oedema. 相似文献

Within a randomized European multicentre trial the time of onset, severity and progression of intracerebral haemorrhages (ICH) were investigated prospectively by serial cranial ultrasonography in 343 ventilated infants with severe respiratory distress syndrome (RDS) following instillation of single or multiple doses of a natural porcine surfactant (Curosurf). In 148/343 infants (43%) ICH was diagnosed (grade I or II: 22%, grade III or IV: 21%). In 26 cases (8%) ICH was present on the ultrasound scan prior to surfactant instillation at a median age of 6h. Incidence and severity of ICH was similar after single- or multiple-dose surfactant treatment. Using a logistic regression model the following risk factors predictive of ICH were defined: low birth weight, allocation to certain hospitals, vaginal delivery, Apgar score6, rectal temperature on admission 36°C, primary anaemia, acidosis prior to treatment, RDS grade IV in pre-treatment chest films and poor response to surfactant treatmentOur study provides supportive evidence that multiple doses of Curosurf do not increase the risk for ICH as compared to single-dose administration.A preliminary report of this work was presented at 8th International Workshop on Surfactant Replacement, Oslo, Norway, May 21 1993. The study was supported by grants of the German government (BMFT 93 607 27) and the German Research Council (Deutsche Forschungsgemeinschaft He 2072: 1–2). The surfactant used in the trial was prepared ang tested in Stockholm with the skilful technical assistance of Elin Arvesen, Bim Linderholm. Eva Lundberg, Gunhild Nilsson and Petru Popa (supported by the Swedish Medical Research Council (Project No. 3351) and Oscar II:s Jubileumsfond)Dedicated to the memory of Edgar (Eddi) Laufkötter, one of the most active trial collaborators, who died under tragic circumstances on April 10, 1994. 相似文献
