The anaesthetist will see you in the ward prior to the operation or in the reception room in theatre. If you have medical problems; eg: heart condition, previous cardiac surgery, chest disease (eg: emphysema), you will be referred to a physician for an assessment and may see the anaesthetist a few days prior to the operation. A premed is sometimes given prior to theatre which will make you a little drowsy and relaxed. In theatre you will sit on the theatre table and make yourself comfortable prior to the induction of anaesthesia. A drip will be inserted into your arm through which the anaesthetic drugs are administered. Gases will be given by a mask and once you are asleep a tube will be inserted into your throat, this is why you may have a sore throat for a short time after the operation.
The anesthetic is a general anaesthetic with a regional block. It can be done with a block alone but you are placed into a seated position on the operating table which can be uncomfortable and thus a general anaesthetic is preferred. The block is done with local anaesthetic injected into the side of the neck where the nerves to the arm are passing (essentially an epidural of the arm). This provides excellent pain relief during the operation thus less anaesthetic drugs are required; you tend to wake up quickly and are quite refreshed afterwards. The block provides excellent relieve of pain after the operation and lasts for between 8 and 24 hours. The arm may be completely dead and you may not even be able to move your fingers initially. Care must be taken not to put anything hot on the arm as this will not be felt and a burn may occur. In approximately 1% of cases there may be a persisting area of numbness in the arm, forearm or hand after the block has worn off. This numbness will usually disappear within 3 months. Occasionally neuralgia (nerve pain) may occur after the block and may require medication till it settles of its own accord. Although extremely rare, permanent nerve damage has been reported.
You tend to wake up very quickly after the operation and may eat soon afterwards. The drip will be taken down when you are back in the ward. The block provides excellent pain relief for between 8 and 24 hours but pain killers and anti-inflammatories are started before the block wears off so that they are already working when the pain starts. Patients vary in the amount of pain killers that they need; some don’t need to take any whereas others may need to take them for up to 6 weeks.
