Serum intact parathyroid hormone as a predictor of hypocalcaemia after total thyroidectomy 总被引:1,自引:0,他引:1
BACKGROUND: Hypocalcaemia from hypoparathyroidism is a complication of total thyroidectomy. The aim of the present study was to determine whether an early postoperative level of serum parathyroid hormone (PTH) after total thyroidectomy predicts the development of significant hypocalcaemia and the need for treatment. METHODS: Patients undergoing total thyroidectomy had their serum level of intact PTH checked 1 h after removal of the thyroid gland. Serum calcium level was checked on the following morning. Oral calcium and/or calcitriol was commenced if the patient developed hypocalcaemic symptoms, or if the corrected serum calcium level was <2.0 mmol/L. RESULTS: Seventy-nine patients were included in the present study. Thirteen patients had symptoms of hypocalcaemia on postoperative days 1 or 2 and 66 patients remained asymptomatic. The postoperative intact PTH, day 1 calcium and day 2 calcium was 0.32 +/- 0.60 pmol/L, 2.01 +/- 0.11 mmol/L, and 2.02 +/- 0.16 mmol/L, respectively, for the symptomatic group and 1.98 +/- 1.25, 2.21 +/- 0.13, and 2.19 +/- 0.14, respectively, for the asymptomatic group. Calcium support was given to 25 patients, of whom 14 also required calcitriol. CONCLUSION: Serum PTH 1-h after total thyroidectomy is a reliable predictor of hypocalcaemia and can allow safe early discharge of patients from hospital. 相似文献

OBJECTIVE: Hypocalcaemia after total or completion thyroidectomy has traditionally required 48 hours or longer inpatient monitoring of serum calcium levels. The use of parathyroid hormone (PTH) levels to predict postoperative hypocalcaemia is well established. This study aimed to measure the impact of a management plan based on postoperative PTH on achieving safe early discharge after thyroidectomy. METHODS: A prospective cohort study of 76 patients undergoing total or completion thyroidectomy was performed. Serum PTH level was measured 4-12 hours postoperatively and used to stratify patients into three groups: normal PTH (> 12 pg/mL), undetectable PTH (< 3 pg/mL) and intermediate PTH (4-11 pg/mL). A subgroup analysis was performed on a cohort of patients after a change in the management philosophy aiming for day 1 discharge based on the postoperative PTH. RESULTS: Seventy-five percent of eligible patients were successfully discharged on day 1 with no complications or readmissions; 21% of patients had intermediate or undetectable PTH levels and were monitored for 48 hours. No patient required intravenous calcium and no patient suffered permanent hypoparathyroidism. CONCLUSION: A single PTH measurement at 4-12 hours postoperatively allows for accurate prediction of patients at risk of hypocalcaemia. Patients with a normal postoperative PTH level can be safely discharged on the first postoperative day. 相似文献

Background: The risk of hypocalcaemia after thyroidectomy has traditionally mandated inpatient monitoring for signs and symptoms as well as frequent measurement of serum calcium levels. In recent years there has been much interest in the published work about the use of intact parathyroid hormone (PTH) to better predict hypocalcaemia after thyroidectomy. Although generally accurate, the use of intact parathyroid hormone in Australia has not become widespread. On behalf of the Australian Endocrine Surgeons an analysis of Australian data on the use of PTH levels to predict hypocalcaemia after thyroidectomy was carried out. The data were analysed with a view to making recommendations about the use of this test in clinical practice and the feasibility of achieving safe early discharge for patients. Methods: Four recently published or presented Australian studies on the use of early postoperative PTH levels after total or completion thyroidectomy to predict post‐thyroidectomy hypocalcaemia were analysed. Patients were stratified into either normal or low PTH groups as defined by the normal ranges set by each laboratory and rates of hypocalcaemia were analysed. Results: A total of 458 patients were examined. Seventy‐six per cent of the patients had PTH in the normal range and hypocalcaemia (serum‐corrected calcium cCa2+ < 2.00 mmol/L) occurred in 17.9% of patients. Sensitivity, specificity and positive predictive values of a normal postoperative PTH level as a predictor of normocalcaemia are 92.6, 70.7 and 92.3%, respectively. Low PTH as a predictor of hypocalcaemia is poor. The overall sensitivity, specificity and positive predictive values are 70.7, 92.6 and 71.6%, respectively. Conclusion: Normal postoperative PTH levels accurately predict normocalcaemia after total or completion thyroidectomy. PTH levels should ideally be drawn 4 h postoperatively and patients with PTH in the normal range can be safely discharged on the first postoperative day. Use of oral calcium supplements, either as needed or routinely, will avoid mild symptoms that may develop in 7% without treatment. 相似文献

Background : Permanent hypoparathyroidism, although a recognized complication of total thyroidectomy, is an outcome that all endocrine surgeons try to avoid. Methods : To minimize the risk of postoperative hypoparathyroidism a strategy was developed of routine autotransplantation of at least one parathyroid gland into the ipsilateral sternomastoid muscle during every total thyroidectomy. One hundred consecutive patients undergoing total thyroidectomy were included in the study. Serum calcium and albumin levels were measured pre-operatively, on the first 2 postoperative days, and after 2 weeks, or until return to normal serum calcium levels without calcium supplementation. If patients developed biochemical evidence or symptoms of hypocalcaemia postoperatively, a calcium replacement was administered according to defined protocol. Results : In 74 cases one parathyroid gland was autotransplanted: 44 for inadvertent removal or anatomical reasons, 19 because of devascularization (assessed by a cut through the gland’s capsule and evaluation of the capillary bleeding pattern), and 11 by protocol. In 25 cases, two or more glands were autotransplanted. Fourteen patients developed symptoms of hypocalcaemia and received calcium supplementation, as did another 13 asymptomatic patients with only biochemical evidence of hypocalcaemia. At follow-up 3 months postoperatively the incidence of permanent hypoparathyroidism was zero, with all patients being normocalcaemic without calcium supplementation. Conclusions : This strategy, easily adopted by any experienced surgeon, has the potential to eliminate permanent hypoparathyroidism following total thyroidectomy. 相似文献

BACKGROUND: Postoperative parathyroid gland function after total thyroidectomy (TT) has traditionally been monitored by the measurement of serum calcium concentrations. The purpose of this study is to determine whether measurement of parathyroid hormone (PTH) concentrations in the early postoperative period accurately predicts patients at risk of developing hypocalcaemia. METHODS: A prospective cohort study of patients undergoing TT was carried out. PTH concentrations were measured preoperatively and at 4 and 23 h postoperatively. Serum calcium concentration was measured preoperatively and twice daily for 48 h after surgery. RESULTS: One hundred patients undergoing TT were recruited into the study in the period June 2004 to July 2005. Benign multinodular goitre was the most common indication for surgery (77%). The incidence of temporary hypocalcaemia (Ca < 2.0 mmol/L) was 18%. The mean PTH concentration at 4 h after surgery was 22.3 ng/L and was not significantly different from the 23-h concentration of 23.2 ng/L (P = 0.18). A PTH concentration of < or = 3 ng/L measured at 4 h after surgery had a sensitivity, specificity and likelihood ratio of 0.71, 0.94 and 11.3, respectively, for predicting postoperative hypocalcaemia. The accuracy of a single PTH concentration at 4 h was good for predicting hypocalcaemia (area under receiver-operator characteristic curve 0.90; confidence interval 0.81-0.96). There was no significant difference in accuracy between the 4- and 24-h PTH concentrations (P = 0.14). CONCLUSIONS: A single measurement of PTH concentration in the early postoperative period after TT reliably predicts patients who are likely to develop hypocalcaemia. This approach facilitates early discharge and may decrease the need for multiple postoperative blood tests. 相似文献

Identification of Patients at Low Risk for Thyroidectomy-Related Hypocalcemia by Intraoperative Quick PTH 总被引:1,自引:0,他引:1
Background Transient hypoparathyroidism is a frequent and challenging complication following total thyroidectomy. The aim of the study
was to identify patients at risk of developing thyroidectomy-related hypocalcemia and symptoms by means of the intraoperative
quick parathyroid hormone (PTH) assay.
Methods Eighty-one patients undergoing total thyroidectomy were included in the study. Quick PTH levels were measured at induction
of anaesthesia and 10 minutes after total thyroidectomy. A sample of 10 patients who underwent unilateral thyroid lobectomy
was considered as a control group. The accuracy of intraoperative PTH decline in predicting postoperative hypoparathyroidism
was analysed.
Results After total thyroidectomy, 27 patients (33.3%) developed postoperative hypocalcemia. Symptoms were reported by 21 patients
(25.9%). The mean percentage decline of intraoperative quick PTH was 81% in hypocalcemic compared with 39% in normocalcemic
patients (P < 0.001), and it was 83% in symptomatic compared with 42% in asymptomatic patients (P < 0.001). Mean proportion decline of quick PTH after unilateral lobectomy was 20%, significantly lower than the 53% registered
after total thyroidectomy (P = 0.005). Analysis of variation of intraoperative quick PTH with the receiver operator characteristics (ROC) curve showed
a 75.7% decline as the cut-off value predicting postoperative hypocalcemia with the highest accuracy (91.4%) (sensitivity:
81.5% specificity: 96.3% positive likelihood ratio: 22; negative likelihood ratio: 0.2). Regarding the prediction of postoperative
symptoms, a 79.5% decline was the most accurate (92.6%) cut-off point (sensitivity: 76.2% specificity: 98.3% positive likelihood
ratio: 46; negative likelihood ratio: 0.2).
Conclusions Quick PTH monitoring during total thyroidectomy is a useful means for identifying low-risk patients for postoperative hypoparathyroidism
and candidates for early, safe discharge. Furthermore, it is an objective method complementary to the surgeon’s judgement
of the intraoperative function of parathyroid glands, which should be implanted in the event of a 75%–80% decline. 相似文献

Postoperative hypocalcaemia is often observed after total thyroidectomy. In patients requiring calcium replacement therapy after 1 year, hypocalcaemia must be considered permanent. The aim of this study was to assess the incidence of hypocalcaemia following total thyroidectomy and to evaluate the risk factors predicting delayed outcome such as hypoparathyroidism. From January 1998 to September 2001, 310 patients underwent total thyroidectomy in our department. In a total of 37 patients experiencing hypocalcaemia, the authors carried out a comparative study of 34 patients with transient hypocalcaemia (group A) and 3 patients with permanent hypocalcaemia (group B). The incidences of transient and permanent hypocalcaemia were 11.9% and 0.9%, respectively. Central neck lymph-node dissection performed in cases of thyroid carcinoma correlated with permanent hypoparathyroidism. The most significant factors predicting long-term outcome of hypocalcaemia were low serum calcium levels (< 8 mg/dl) and high serum phosphorus levels (> 5 mg/dl) measured on postoperative day 7, despite oral calcium replacement. The indications for lymph-node dissection in the central neck area should be very strictly selected. When delayed serum calcium and phosphorus levels are unfavourable, thorough follow-up of patients is mandatory in order to administer the correct therapy and prevent the consequences of chronic hypocalcaemia. 相似文献

The aim of the study was to evaluate the efficacy of parathyroid hormone 1-hour assay for the early prediction of hypoparathyroidism after thyroidectomy. Candidates for total, subtotal, completion thyroidectomy or lobectomy were entered into the study. Pre- and postoperative calcium and parathyroid hormone (1 hour and postoperative day 1 after thyroidectomy) levels and clinical hypocalcaemia were recorded. Patients were divided into 3 groups and 2 subgroups: 1. patients who underwent lobectomy (control group); 2. patients who underwent total thyroidectomy with postoperative hypocalcaemia (2A: asymptomatic patients, 2B: symptomatic patients); 3. asymptomatic patients with normal calcium levels after total thyroidectomy. Of 119 patients, 109 underwent total thyroidectomy and 10 lobectomy. Of the 109 patients submitted to total thyroidectomy, 35 (32.11%) developed postoperative transient hypocalcaemia. Twenty-one patients (19.27%) were asymptomatic and 14 (12.84%) were symptomatic. Parathyroid hormone levels decreased after 1 hour in group 3 (32.98 pg/dl), 2A (9.84 pg/dl) and 2B (7.46 pg/dl). There was no significant difference in parathyroid hormone levels at 1 hour between group 2A and 2B (p = 0.06), but were significantly lower compared to groups 3 and 1 (p < 0.05). Parathyroid hormone levels at 1 hour after total thyroidectomy is a good predictor of early hypocalcaemia. It might be more useful than serum calcium monitoring for the early identification of patients requiring postoperative calcium supplementation. 相似文献

Rolle der totalen Thyreoidektomie im primären Therapiekonzept der benignen Knotenstruma 总被引:8,自引:0,他引:8
INTRODUCTION: After subtotal resection of multinodular goiter, rates of up to 40% are reported for recurrent goiter in the long-term follow-up. Because of the increased morbidity of surgery for recurrent goiter, this study evaluated the preconditions that would justify total thyroidectomy as part of the primary therapy concept for benign multinodular goiter. MATERIAL AND METHODS: The Quality Assurance Study of Benign and Malignant Goiter covering the period from 1 January to 31 December 1998 assessed 5195 patients treated for benign goiter by primary bilateral resection. With respect to the extent of resection three groups were analyzed: bilateral subtotal resection (ST+ST, n=4580), subtotal resection with contralateral lobectomy (ST+HT, n=527), and total thyroidectomy (TT, n=88). RESULTS: The age of the patients was significantly higher (60.3 years) in the TT group than in the ST+ST (52.5 years) and ST+HT (55.6 years) groups. ASA classification grades III and IV were significantly more frequent in the TT group. The postoperative morbidity increased with the extent of resection. The rate of permanent recurrent laryngeal nerve (RLN) palsy was 0.8% for ST+ST, 1.4% for ST+HT, and 2.3% for TT and of permanent hypoparathyroidism 1.5% for ST+ST, 2.8% for ST+HT, and 12.5% for TT. Multivariate analysis showed that the extent of resection significantly increased the risk of RLN palsy (transient RR 0.5, permanent RR 0.4) and hypoparathyroidism (transient RR 0.2,permanent RR 0.08). The surgeon's experience (RR 0.6) and identification of the RLN (RR 0.5) reduced the risk of permanent RLN palsy. Additionally, the development of permanent hypoparathyroidism was reduced if at least two parathyroid glands (RR 0.4) were identified. CONCLUSION: Total thyroidectomy is associated with an increased rate of RLN palsies and hypoparathyroidism in comparison to less extensive thyroid surgery. In the hands of well-trained surgeons using an appropriate intraoperative technique, primary thyroidectomy is justified if the patient has an increased risk of recurrent goiter. Due to the increased postoperative morbidity after total thyroidectomy, subtotal thyroid resection based on the morphologic changes in the thyroid gland is still recommended as the standard treatment regimen for multinodular goiter. 相似文献
