Objective To find the relevant factors that can influence the results of Ritleng lacrimal duct intubafion surgery, apply effective nursing intervention measures, and cooperate with the success conduct of operation and perioperation. Methods 102 patients who underwent Ritleng lacrimal duct intubation were analyzed in our study. The relevant factors were found out, then various corresponding nursing intervention measures before and after the surgery were used in 293 patients that underwent the same operation from May 2007 to February 2008. Results After applying the effective nursing intervention measures, the cure rate of these 293 patients was 95.9%. Silicone tube was never broken in the operation. Conclusions Applying various corresponding nursing intervention measures before and after Ritleng lacrimal duct intubation can improve the success rate of surgery and reduce the complications.

Objective To evaluate the effect of protecting parathyroid glands in situ in the operation of total thyroidectomy by detecting parathyroid hormone after the operation.Methods In the surgical team, 1019 consecutive patients with thyroid diseases were treated with total thyroidectomy.During the operation, parathyroid glands were protected in situ with correctly identifying the parathyroid glands, precisely dissecting its envelope and protecting its blood supply.Serum calcium level and parathyroid hormone were measured before and 24 hours after operation. The patients who had symptomatic hypocalcemia or hypoparathyroidism were given supportive treatment and followed-up. Results At least one of the parathyroid glands was preserved and remained in situ in all cases.Eighty-nine cases (8.7%) had decreased parathyroid hormone levels and 42 cases (4.1%) had complicated symptomatic hypocalcemia.The symptoms of hypocalcemia in all these cases could be controlled by supportive treatment, and serum calcium level and parathyroid hormone had all recovered 1 - 6 months later.If 3 and 4 parathyroid were conserved in situ, the postoperative complication rate was significantly lower than those with 1 and 2 parathyroid conserved(decreased PTH 69/999 vs 20/20, symptoms of hypocalcemia 25/999 vs 17/20, all P <0.01).Conclusion The techniques to protect parathyroid glands in situ are effective measure to prevent the postoperative hypoparathyroidism in total thyroidectomy.
