Background
Craniotomy and excision of tumours can produce neurological deficits if the tumour is located close to eloquent areas of the brain. One technique of overcoming this problem is to keep the patient ‘awake’ during surgery.Methods
Eight patients with intra cranial space occupying lesions (ICSOL) were operated ‘awake’, using a combination of skull block with sedation and analgesia. A mixture of 0.125% bupivacaine and 0.5% lignocaine was used for various nerve and field blocks. Midazolam, fentanyl and propofol in titrated doses were used to achieve conscious sedation.Result
The procedure was successful in all the patients. They tolerated the procedure well and were able to follow the commands intraoperatively as desired. There were no significant complications.Conclusion
Awake craniotomy with skull blocks with sedation and analgesia is a well established procedure. It requires a good rapport between surgeon, anaesthesiologist and the patient.Key Words: Awake craniotomy, Skull block, Sedation, Analgesia 相似文献73.

Objective
To determine the frequency of anterolateral ligament (ALL) injury in patients with acute anterior cruciate ligament (ACL) rupture and to analyse its associated injury patterns.Methods
Ninety patients with acute ACL rupture for which MRI was obtained within 8 weeks after the initial trauma were retrospectively identified. Two radiologists assessed the status of the ALL on MRI by consensus. The presence or absence of an ALL abnormality was compared with the existence of medial and lateral meniscal tears diagnosed during arthroscopy. Associated collateral ligament and osseous injuries were documented with MRI.Results
Forty-one of 90 knees (46 %) demonstrated ALL abnormalities on MRI. Of 49 knees with intact ALL, 15 (31 %) had a torn lateral meniscus as compared to 25 torn lateral menisci in 41 knees (61 %) with abnormal ALL (p?=?0.008). Collateral ligament (p?≤?0.05) and osseous injuries (p?=?0.0037) were more frequent and severe in ALL-injured as compared with ALL-intact knees.Conclusion
ALL injuries are fairly common in patients with acute ACL rupture and are statistically significantly associated with lateral meniscal, collateral ligament and osseous injuries.Key Points
? ALL injuries are fairly common in patients with acute ACL rupture. ? ALL injuries are highly associated with lateral meniscal and osseous injuries. ? MRI assessment of ACL-injured knees should include evaluation of the ALL.76.

Recent studies have shown that hyperhomocysteinaemia is a common, independent and easily modifiable risk factor for atherosclerotic and thromboembolic diseases such as cerebrovascular disease, coronary artery disease and venous thrombosis. The vascular risk rises continuously across the spectrum of elevated plasma homocysteine concentrations. It is at least as important as cholesterol, lipoprotein abnormalities and hypertension and should be part of risk assessment, especially those at high risk. Moderately elevated plasma homocysteine concentration is readily correctable by folic acid, betaine, or vitamin B12 supplementation. It seems logical to assume that a reduction in homocysteine concentration will reduce the risk of ischaemic stroke, but there are as yet no published data to prove this. This review will discuss the aetiology and possible treatment of hyperhomocysteinaemia causing ischaemic stroke. 相似文献

在美国,食管癌是死亡率最高的恶性肿瘤之一,男性多于女性,其发病率随年龄增长而增加。食管癌临床表现早期食管癌临床表现不明显,吞咽困难是最常见的初始症状,但由于食管壁的柔韧性,病人到晚期才感觉到,从不能吞咽固体开始,进展到最终不能吞咽液体。此外,病人还可有吞咽时疼痛、体重减轻、营养不良和虚弱等表现。晚期表现还包括胸骨后疼痛、呃逆、呼吸困难、胃烧灼感、口臭、声音嘶哑、咳嗽、流涎过多及夜间误吸等。食管切除术后病人的护理食管切除术后24~48 h病人在重症监护室度过,通常带有气管插管等多种导管,护士应加强心肺及各方面的监护… 相似文献

Ectopic pancreatic tissue has the same characteristics than normal pancreatic tissue.Therefore it may be affected by the same diseases. We report a rare cause of epigastric pain due to gastric heterotopic pancreatitis.The rare diagnosis was suspected by ultrasound and CT and definitively confirmed by echo-endoscopic guided biopsies. 相似文献
