Pancreatic cancer remains a devastating disease with an average 5-year survival rate of about 3-5%. Previous retrospective studies showed that perioperative epidural block and/or dexamethasone are associated with improved outcome after cancer surgery. This randomized trial aims to investigate the effect of perioperative epidural block and/or dexamethasone on long-term survival in patients following pancreatic cancer surgery.
epidural block is today the most common method of pain relief during labor. With increased use of epidural analgesia, many women are found in the second or third pregnancy and require repeated epidural analgesia. But there was a higher incidence of unilateral blockade among women receiving their repeated epidural which causes patient unsatisfaction. Objectives: Examination of the performance and outcome of women receiving their first versus repeated epidural block. Patients and methods: The study included 140 American Society of Anesthesiologists (ASA) Physical Status II patients (age range 20 to 40 years) and scheduled for normal vaginal delivery. The patients were divided randomly into two equal groups. Group (A) in which 70 women primipara subjected to their first epidural block while group (B) in which 70 women multipara subjected to their repeated epidural block. For each patient, the following data were collected: demographic data, details of labor (gestation, cervical dilatation), visual analogue scale (VAS) before the epidural and 30 minutes after injection of local anesthetic and incidence of unilateral block.
Continuous Paravertebral block (PVB) was reported to provide less episodes of hypotension than continuous thoracic epidural block (TEB). The maintenance of optimal tissue perfusion is essential for esophageal anastomosis in patients undergoing oesophagectomy. the aim of this study is to compare Hemodynamic effect of continous PVB compared to TEB , in patient undergoing oesophagectomy with laparoscopy and thoracotomy.
Local anaesthetics are highly toxic drugs. They can cause toxicity by an absolute overdose, accidental injection in a blood vessel or slow absorption from the area of injection. The risk of toxicity when performing regional anaesthesia can be reduced significantly by injecting the optimal dose of local anaesthetic at the correct site. To date most of the local anaesthetic dose finding studies for epidural labour analgesia has focused on ED50 ( the dose effective in 50% of patients). The purpose of this research study is to find out the ED95 dose (the dose effective in 95% of patients) of local anaesthetic for epidural analgesia in labour. The dose determined from this research trial will guide the anaesthetists to the optimal starting dose of the local anaesthetics for epidural analgesia in labour. This would lead to decreased chances of toxicity and will improve patient safety. We aim to recruit a total of 100 pregnant patients in early labour (cervical dilatation ≤ 5 cm) requesting epidural analgesia to answer the research question based on the continual reassessment method. Patients will be recruited according to well-defined criteria. They will be fully informed about the study and have the choice of not participating or opting out at any time during the study. It is not going to affect the kind of treatment they receive. The experts in the field with full safety precautions will perform this study at St James' Hospitals, Leeds.
