Description
Technical field：
The utility model relates to a kind of negative-pressure detection devices of caudal anaesthesia, belong to field of medical device.
Background technique：
Caudal anaesthesia (also referred to as epidural block):It is a kind of one of anaesthesia technology for being widely used in clinic, because of its tool
Have the characteristics that influence small, exact analgesic effect, flesh pine to cardiovascular, breathing and gastrointestinal function it is good and economic, practical, one
Directly have the function of can not be substituted in clinical anesthesia and pain therapy.Epidural block range：Neck, chest, abdomen, waist bottom,
Perineum, the surgery anesthesia of lower limb and foot, Postoperative Analgesia After, inhibiting pain in parturition, pain therapy are gone back General anesthesia at present and are used for
Chest, major abdominal surgery etc..
Caudal anaesthesia includes two links of cavum epidural puncture and Epidural catheterization.
Cavum epidural puncture still generallys use blind spy property operation (the traumatic operation of i.e. non-photopic vision), relies primarily on master
Perception is felt and therefore the positioning of micro-judgment puncture needle mainly judges to puncture using resistance disappearance method, sessile drop method or glass-tube method
Positioning of the needle in epidural space；
But resistance disappearance method is to penetrate ligamentum flavum according to anesthesia spinal needle, needle mouth is infused when entering epidural space
Emitter resistance reduces suddenly, disappears, and liquid swimmingly injects epidural space in syringe, and the minute bubbles in syringe are not pressed
Contracting prompts anesthesia spinal needle to enter epidural space.When sessile drop method and glass-tube method are that anesthesia spinal needle enters epidural space
It may occur in which negative pressure appearance：When needle point enters epidural space, the drop water or glass liquid in pipe connect on the needle base of a fruit can be inhaled into, and
It is considerable to find liquid level in glass-tube and fluctuated with breathing, but sessile drop method and wave duct method can also have false negative pressure appearance, as puncture needle enters
Gap or Minor articulus are intracavitary by vertebra, are likely to occur negative pressure appearance, and negative pressure is not identical in different segment epidural space, dura mater
External series gap negative pressure occurrence rate is with neck and chest epidural space highest, and about 98%, waist takes second place for 88.3% [4], canalis sacralis
There is not negative pressure, and the negative pressure of epidural space is influenced by certain factors, such as cough, hold one's breath, gestation can all make dura mater
External series gap negative pressure becomes smaller, disappears；No matter therefore taking which kind of method is indirect non-specific method, relies primarily on subjective sensation and warp
It tests, part ligamentum flavum is thin or fusion on middle line is bad, and the feeling that puncture needle wears out ligamentum flavum can be unobvious, comes only according to feel
Judge that epidural space may accidentally wear endorchis, therefore the reliability of above-mentioned current methods is only capable of reaching 70%~80% or so.
Epidural catheterization is that epidural catheter is built into epidural space through puncture needle after the completion of cavum epidural puncture,
It is also a kind of blind spy property operation, therefore, after the completion of epidural puncture sets pipe, before epidural injection, is frequently utilized that fiber crops
The toxic reaction of liquor-saturated drug, using " epidural space tested number method " as cavum epidural puncture, the secondary monitoring for the positioning for setting pipe
Method, still, if cavum epidural puncture, setting pipe and mistake occur, such as conduit is strayed into cavum subarachnoidale or blood vessel, will result in
When the local anaesthetics of caudal anaesthesia dosage accidentally injects cavum subarachnoidale full spinal anesthesia can occur immediately for serious complication
(generate whole somatic nerves in a short time and sympathetic nerve be blocked, i.e., and respiratory heart stop jumping is stopped, consciousness disappears)；When hard
The local anaesthetics of the outer anaesthesia dosage of film, which is accidentally injected into, intravascular there is the slight or serious local anaesthetics toxic reaction of intravascular injection
(happen suddenly frightened Jue, consciousness disappear, Muscle tensility is high, and muscular tremor, respiratory heart stop jumping is stopped), epidural space bleeding (incidence 9.6%-
25.9% or so) local anaesthetics general toxic reaction caused by and full spinal anesthesia can when finding and being effectively treated not in time
Patient is caused to be disabled or dead.
Meanwhile epidural space has plexus vasculosus abundant, cavum epidural puncture and Epidural catheterization are possible to damage quiet
Arteries and veins clump and bleeding, are easy to produce epidural hematoma after bleeding, once epidural hematoma formed compressing spinal cord be more than 24 hours will production
Raw irreversible damage.The diagnosis of epidural hematoma relies primarily on clinical symptoms, sign and imageological examination, once it makes a definite diagnosis necessary
Implement operation in 6h~8h, remove hemotoncus, releases compressing.It avoids that the damage of spinal cord irreversibility occurs, spinal compression is more than 8h
Then prognosis is bad.
Blind spy method sets complication of anesthesia caused by angiorrbagia etc. without epidural puncture caused by objective anesthesia indication, so far
It is still complication of anesthesia and the main source of anesthesia accident.
