background: establishment of a patent airway and preserving spontaneous ventilation is a necessity in predicted difficult airway. airway regional blocks are commonly used in predicted difficult airway but the known limitations of these techniques propose the need to suggest alternative methods. this study compares subcutaneous dissociative conscious sedation (sdcs); a recently reported method o...

awake intubation is the choice for airway management in anticipated difficult airway (da), which means establishing airway without induction of deep sedation; however, in cases where sedation is precarious, decision in emergency situations, success in awake intubation is dependent on proper regional airway block. a 21 year old man with bilateral temporo-mandibular ankyolosis and a 25 years old ...

Ludwig’s angina is a potentially lethal, rapidly spreading cellulitis involving the sublingual and submandibular spaces leading to difficult airway. Associated pregnancy makes airway management and choice of anesthesia further difficult. There are previously reported cases of drainage of Ludwig’s angina in pregnant woman managed with superficial cervical plexus block and other regional techniqu...

Anesthesia options for upper extremity surgery include general and regional anesthesia. Brachial plexus blockade has several advantages including decreased hemodynamic instability, avoidance of airway instrumentation, and intra-, as well as post-operative analgesia. Prior to the availability of ultrasound the risks of complications and failure of regional anesthesia made general anesthesia a mo...

Subarachnoid block is commonly used regional anesthetic technique for patients who require surgical anesthesia for lower extremities, perineum, pelvic girdle or lower abdomen. It may be useful in patients with difficult airway or suffered from co-morbidities of severe respiratory disease. Spinal anesthesia covering the mid-thoracic level yields a contracted small intestine to provide superior s...

Patients with Noonan syndrome are characterized by many anesthetic problems, primarily related to potential difficult airway and technical issues with regional anesthesia. We describe the anesthetic management of a difficult case of a parturient with Noonan syndrome requiring emergency Cesarean section under spinal anesthesia. We had to evaluate the patient within a limited amount of time becau...

Background: Regional anesthesia avoids airway instrumentation, preserves conscious level and provide rapid recovery with significant postoperative analgesia. There has always been a search for adjuvants to the regional nerve block drugs that prolong duration of analgesia but lesser adverse effects. The ideal additive still continues, therefore in this study, we investigated effects addition dex...

complex regional pain syndrome (crps) is a variety of painful conditions following injury which appears regionally having a distal predominance of abnormal findings. this study, evaluate the use of phentolamine for sympathetic block and regional anesthesia in treatment of crps related pain. in this study, 68 patients with crps who were referred to pain clinics of imam hossein and akhtar hospita...
