Lynette McMorrough, 53, has had roles in Crossroads and daytime soap Doctors, but was playing the role of the Fairy Godmother at the Thameside Theatre in Grays, when she became ill on 29 December.
Ms McMorrough was taken to Basildon University Hospital, where after an assessment including a CT scan, she was identified as a patient who could be thrombolysed.
Beth Smyth, specialist nurse for stroke at the hosptial, said: ‘We started thrombolysing patients in Mid-September 2008 and since then we have assessed 35 patients and six have been given the treatment.
‘Early intervention by the nursing specialist team makes sure the damage is limited. Thrombolysing the patient dissolves the blood clot, helping to prevent lasting disabilities and allows for a better recovery,’ he added.
Jennifer Marshall, ward manager for Pasteur Ward, the hospital’s acute stroke unit, said: ‘We are not yet able to thrombolyse patients 24/7 but we hope this is something we can offer in the future.’
