Operating conditions for ocular surgery under general anaesthesia: an eccentric problem

Thyroid surgery under local anaesthesia: an alternative to general anaesthesia

Background: Local Anaesthesia is now being accepted universally as a safe alternative to general anaesthesia for thyroid surgery. Aim: This study was carried out to compare the outcomes of patients undergoing thyroid surgery under local and general anaesthesia. Material and Methods: Hundred patients who underwent thyroid surgery for benign and malignant diseases under local and general anaesthe...

A new operating microscope for ocular surgery.

Bradycardia during cold ocular irrigation under general anaesthesia: an example of the diving reflex.

A case of bradycardia is reported which was precipitated by cold normal saline applied to the eye during general anaesthesia. The history and physiology of the diving reflex is discussed and we believe that these data suggest that this patient's bradycardia was induced by the diving reflex, and not by the oculocardiac reflex.

Field block: an additional technique of potential value for breast surgery under general anaesthesia.

artefacts, such as arterial blood sampling, were removed manually. The respiratory variability of the arterial pressure was compared with the variability of the plethysmograph trace in several ways. Twenty-second epochs (enclosing at least three respiratory cycles) were used to determine the periodic variability. An adjustment to the raw waveform data was made to compensate for any general upwa...

General anaesthesia in ophthalmic surgery.

MANY ophthalmic operations can be performed under local analgesia and this technique is used with satisfaction in all parts of the world today; in fact many surgeons and consultant anaesthetists are satisfied that the best results are obtained by this method. On the other hand, general anaesthesia is used much more than formerly and in some centres it is used routinely for most operations, incl...
