Embodiment Construction

[0028] according to figure 1 , the superficial skin of patient 1 is divided into different dermatomes, which are labeled with reference numerals, eg Th2, L3 and C4. Place temperature sensors 2 on certain skin areas. The temperature sensor 2 is connected to an analog-to-digital converter 4 via an amplifier 3 having at least 8 channels. An analog-to-digital converter 4 scans the output channels of the amplifier 3 and converts the amplified analog measurement signal into a digital signal.

[0029] The analog-to-digital converter 4 is connected to the PC 5 . The PC 5 determines whether the skin temperature measured by the temperature sensor 2 rises by about 2 to 3° C., as shown in the temperature-time graph 6 . If the PC 5 determines a rise of 2 to 3°C, the PC 5 calculates that painlessness occurs in approximately 2 to 3 (up to 6) dermatomes closer to the foot. The dermatomes that are to be determined pain-free are shown on the display 7 as body images 8 .

Abstract

The invention relates to a device for monitoring the success of spinal anesthesia having at least one electronic temperature sensor for measuring the skin surface temperature within at least one dermatome of a patient; an electronic analysis device connected to the at least one temperature sensor and designed so that it monitors the measurement signal provided by the at least one temperature sensor to determine whether the skin surface temperature increases by about 2 to 3 DEG C; and a display device optically and / or acoustically indicating the result of the analysis by the electronic analysis device.

Description

technical field [0001] The subject of the present invention is a device and a method for effect testing of spinal cord paralysis in medical treatment. Background technique [0002] Spinal palsy is a local anesthesia near the spinal cord. Signal transmission to the nerves originating from the spinal cord is blocked by injecting a local anesthetic at lumbar spinal level into the hydrocephalus (Hirnwasserraum). This temporarily and reversibly blocks the sympathetic nervous system, sensory and motor functions of the lower body. [0003] As a standard method of anesthesia, spinal palsy is now used in a large number of abdominal, pelvic, lower extremity, and obstetric procedures, and in these procedures as a backup or alternative to other local methods such as perilesional anesthesia and general anesthesia. [0004] The human spine is made up of 34 vertebrae connected by strong ligaments and surrounding the spinal cord. Between the vertebrae there are spinal nerves which innerv...
