Abstract:

Objective To observe the effect of ultrasound-guided transverse abdominis block anesthesia on stress response in patients with colon cancer after laparoscopic surgery. Method 80 patients with colon cancer undergoing laparoscopic surgery in Yichang Fifth People's Hospital from August 2019 to August 2021 were randomly divided into control group (routine anesthesia, 40 cases) and observation group (ultrasoundguided transverse abdominal block anesthesia, 40 cases). The sedation, pain, stress index, immune function and hemodynamics were compared between the two groups. Result Compared with the control group, the Ramsay score and visual analogue score of the patients in the observation group were lower, and the stress index, immune function and hemodynamics were improved significantly (P ＜ 0.05). Conclusion Ultrasound-guided transverse abdominis block anesthesia in laparoscopic colon cancer patients can achieve better sedative effect, reduce pain and stress response, maintain good hemodynamics, and promote the improvement of postoperative immune function.
