PHTY205 Lecture Notes - Lecture 12: Nerve Block, Orthopedic Surgery, Local Anesthetic
Document Summary
Describe the different types of anaesthesia that can be used: anaesthesia. Is a combination of: amnesia, analgesia (pain control, muscle relaxation, to allow the performance of surgery or interventional procedures, types, general, complex surgical procedures. Induction: propofol, ketamine, maintenance, volatile or intravenous anaesthetics, volatile gases are cold and drying, emergence, waking up, reduce drugs slowly, neuroaxial, regional, and patient is awake. Small gauge needle inserted into the subarachnoid space and local anaesthetic introduced. Smaller volume of local anaesthetic required: epidural, placement of a small gauge catheter into the epidural space, benefits, decreased incidence of thrombotic complications dvt, pe, chronic respiratory conditions, complications, post-dural puncture headache, vasodilation. Spinal haematoma: peripheral nerve block, used for procedures involving the extremities e. g. orthopaedics, brachial plexus, axillary block, sciatic nerve block. Discuss the complications of anaesthesia: non-pulmonary post-operative complications, cardiovascular instability, co & bp, blood volume deficit. Smoking history, previous dvt/pe: clinical diagnosis: unreliable. Fever, temp of limb, pain, swelling: venogram, doppler us etc.
