Abstract

The invention relates to the technical field of medical treatment and public health, and provides a method and device for conveniently and efficiently identifying cerebrospinal fluid in intraspinal anesthesia operation, and the method comprises the following steps: 1, understanding the spectroscopy characteristics of cerebrospinal fluid, local anesthesia drugs and normal saline; 2, exploring ATR-FTIR spectral characteristic discrimination indexes of cerebrospinal fluid, local anesthesia drugs and normal saline, and establishing a diagnostic standard; 3, further expanding and constructing a characteristic atlas database; and 4, carrying out Fourier transform infrared spectroscopic analysis on a liquid sample obtained in the intraspinal anesthesia operation by adopting a handheld portable infrared spectrometer, obtaining a corresponding liquid sample atlas according to relative vibration and molecular rotation information among atoms in molecules of the liquid sample, and comparing the liquid sample atlas with the characteristic atlas database to obtain a comparison result, and judging whether the liquid sample is cerebrospinal fluid, local anesthesia medicine or normal saline according to the comparison result through an ATR-FTIR spectrum judgment standard.

Description

technical field [0001] The invention relates to the field of medical and health technologies, and more specifically relates to a portable and highly efficient method and device for identifying cerebrospinal fluid during intraspinal anesthesia operations. Background technique [0002] Neuraxial anesthesia is mainly used in patients suitable for abdominal, pelvic and lower extremity surgery. During the operation in the spinal canal, first use local anesthetic (lidocaine) for layer-by-layer infiltration anesthesia to avoid pain caused by subsequent operations. After proper local anesthesia, use a thicker epidural puncture needle (17G) to pass through the skin, subcutaneous tissue, supraspinous ligament, interspinous ligament, and ligamentum flavum in sequence to reach the epidural space and pull out the needle core. Inject normal saline bubbles into the epidural space through the needle without resistance. When there is no resistance, it is determined that the needle tip has r...
