Objective To analyze the clinical effect of ultrasound-guided quadratus lumborum block(QLB)and erector spinae plane block(ESPB)in elderly patients with laparoscopic colorectal cancer surgery.Methods A total of 75 elderly patients who underwent elective laparoscopic radical resection of colorectal cancer in wenzhou central hospital,from August 2021 to March 2022 were selected and divided into quadratus lumborum group(group Q,n=25),erector spinae muscle group(group E,n=25)and group C(n=25).Group Q received QLB combined with general anesthesia,group E received ESPB combined with general anesthesia,the group C was given tracheal intubation with total intravenous general anesthesia.The perioperative anesthesia and analgesic dosage,postoperative recovery quality,resting and cough visual analogue scale(VAS)scores were compared among the groups.Results In contrast to the group C,the number of effective PCIA compressions,the dose of sufentanil,and the analgesic rescue rate were significantly decreased in groups Q and E(P<0.05);In contrast to the the group C,the spontaneous breathing,eye opening and tracheal extubation time of patients in group Q and group E were apparently shortened(P<0.05),and patients in group Q and group E recovered indoor nausea and vomiting,lethargy,restlessness and respiratory depression The number of cases was apparently reduced(P<0.05);at each time point from 2 to 48 hours after operation,compared with the group C,the VAS scores at rest and cough in groups Q and E were apparently decreased(P<0.05).However,there was no significant difference in the above indicators between the group Q and the group E(all P>0.05).Conclusion Ultrasound-guided QLB and ESPB for laparoscopic colorectal cancer surgery can both improve the quality of recovery and achieve satisfactory analgesia in elderly patients.

Objective To investigate the clinical value of color doppler ultrasound in the diagnosis of thrombus of lower extremity veins. Methods A total of 84 patients with thrombus of lower extremity veins(DVT) underwent color Doppler ultrasound and digital subtraction angiography (DSA), and analyzed the test results comparatively. Results Color doppler ultrasound diagnosed deep vein thrombosis(DVT) in 68 cases of all 84 patients, 49 cases were in the left low-er extremity (72.1%), 19 cases were in the right lower extremity (27.9%),patients were in the left more than in the right;In all 68 patients,39 cases were in acute stage,20 cases were in sub acute stage, 9 cases were in chronic period. DSA diagnosed lower extremity DVT in 66 cases in 68 cases diagnosed by color doppler ultrasound,DSA diagnosed lower extremity DVT in 64 cases, 4 cases that examined by DSA were negative. Color doppler ultrasound diagnosed normal in 18 cases, DSA found lower extremity DVT in 2 cases. Compared with the results of DSA examination, the sensitivity and the specificity of color doppler ultrasound for diagnosing DVT were 96.97% and 88.9%, the diagnostic consistency of both methods was high (Kappa=0.78). Conclusion Color doppler ultrasound is simple, fast and repro-ducible, it is high in consistency with DSA and has important value in the diagnosis of lower extremity DVT.
