Abstract:

Objective

To investigate the effects of ultrasound-guided lumbar muscle block and erector spine muscle plane block on stress indicators, inflammatory factors, and T lymphocyte subsets in patients with colorectal cancer after laparoscopic radical surgery.

Methods

From May 2023 to May 2024, 92 patients who underwent laparoscopic radical surgery for colorectal cancer in Xi'an International Medical Center Hospital were selected for observation and study. All samples were assigned into two groups using a random number table method. The experimental group (n=46) received ultrasound-guided lumbar muscle block, while the control group (n=46) received ultrasound-guided erector spine muscle plane block. The stress indicators, inflammation indicators, T lymphocyte subsets, pain scores, cognitive function, and adverse reaction events of the two groups were compared.

Results

After treatment, the CD4+ and CD4+/CD8+ in the two groups were significantly increased (P<0.05), and the increase in the experimental group was better than that in the control group (P<0.05). After treatment, the levels of cortisol, angiotensin Ⅱ, and CD8+ in the two groups were significantly decreased (P<0.05), and the reduction in the experimental group was better than that in the control group (P<0.05). Compared with the control group, the experimental group showed a decrease in tumor necrosis factor-α, interleukin-6, and C-reactive protein levels 12 hours after surgery (P<0.05). The visual analog scale score of the experimental group was obviously lower than that of the control group at 2 and 12 hours after surgery (P<0.05). The Mini Mental State Examination (MMSE) of the experimental group was obviously higher than that of the control group 12 hours after surgery (P<0.05). The incidence of adverse reactions was not statistically obviously different between the two groups (P>0.05).

Conclusion

Ultrasound-guided lumbar muscle block is superior to ultrasound-guided erector spine muscle plane block in reducing stress response, inhibiting inflammatory cytokine production, and improving immune regulation in patients with colorectal cancer after minimally invasive radical surgery, with obvious comprehensive effects.
