Objective To observe the effect of combination of dexmedetomidine and sufentanil on postoperative analgesia for the highly nicotine dependent patients undergoing esophagectomy. Methods Ninety highly nicotine dependent patients undergoing esophagectomy were randomly allocated into three groups (n = 30 each): low-dose sufentanil group (Group S1), high-dose sufentanil (Group S2), dexmedetomidine and sufentanil group (Group DS). All patients of three groups received postoperative PCIA with following setting: 2 mL/h;bolus: 2 mL; lock time: 5 min; 4 hours limited: 40 mL. The scores of VAS and Ramsay, effective presses/total presses of PCIA, the consumption of sufentanil during 72 h after operation, side effects and the satisfaction degree of patients were recorded. Results Compared with those of group S2, the scores of VAS (both at rest and movement) decreased significantly in group DS from 1 h to 8 h (P<0.05). Compared with those of group S1, the scores of VAS (both at rest and movement) decreased significantly in group S2 and DS from 1 h to 72 h (P<0.05). Compared with that in group S1 and S2, the consumption of sufentanil during 72 h after operation decreased significantly in group DS (P < 0.05). Compared with those in group DS, The numbers of nausea and vomiting were significant decreased in group S1 and S2(P < 0.05). Compared with those in group S1, the remedial cases were significantly decreased in group S2 and group DS (P < 0.05). Conclusion The effect of combination of dexmedetomidine and sufentanil is superior to that of sufentanil in terms of postoperative analgesia in highly nicotine dependent male patients undergoing esophagectomy.

Objective To evaluate the effects of the administration of intracoronary diltiazem before the occurrence of no-reflow during direct PCI. Mtthods One hundred and thirty four AMI patients hospitalized from June 2001 to November 2003 were selected as research objects. 60 patients with AMI received intracoronary diltiazem before the occurrence of no-reflow during direct PCI. 74 AMI patients did not receive intracoronary diltiazem and were enrolled as control subjects. Patients with refractory low blood pressure and complete atrioventricular block before PCI were excluded. Thrombolysis in Myocardial Infarction (TIMI) flow grade, corrected TIMI frame count (CTFC) were assessed during angiography, before and after PCI. Results The two groups had similar baseline. There were significant difference in post-PCI no reflow assessment (P = 0.04) and CTFC (P = 0.00). Conclusion Early administration of intracoronary diltiazem during direct PCI reduces the no reflow occurrence.

In recent years, the emergence of single-port laparoscopic technology promoted the development of the technology of laparoscopy, but deficiencies like equipment conflict or lack of triangulation severely hampered the clinical application of this technology. The appearance of single-port laparoscopic flexible instruments makes up for those deficiencies to a great extent. The element is to add a wrist joint to the tip of the instrument to form triangulation and reduce equipment conflict. But this technique is still in an early stage of development. The purpose of this article is to summarize the characteristics and problems of existing flexible single-port laparoscopic instruments, and to provide information for the further improvement, finally the future development was expected.
