Abstract:

The purpose of this research was made necessary by the progressive increase in costs for medical assistance, together with a decrease in the number of available hospital beds and therefore raising the necessity for a shorter stay in hospital and safe hospital discharge. Methods: This research is based on a study group of 206 patients, who had recently undergone total thyroidectomy surgery due to different pathologies (functional or non functional goiter, Basedow disease, differentiated carcinoma, medullar carcinoma). In order to discharge the patients safely within 24 hours after surgery, not well accepted by all the patients – the serum calcium level was postoperatively measured at regular intervals, after  6, 12 and 18 hours. We used the variance analysis of the 3 samples, utilizing the p-value to verify the possibility of reducing the necessary number of blood samples to two when calculating the risk factor of hypocalcemia. Conclusion: We can consider the evaluation of the calcium level at 6 and 18 hours, sufficient to establish a calcium trend. All the patients who had registered a positive or doubt trend of calcium levels can be discharged the day after surgery, with minimum risk of subsequent hypocalcemia. The cases that registered a negative trend of calcium levels during the recovery, can not be considered as certain indicator of late hypocalcemia and therefore it is necessary to measure the PTH level, which gives highly predictive values both in scientific literature and also in our research: in 93,5% of the cases, a correlation between the PTH levels and an eventual development of hypocalcemia was noted.
