Autonomic dysreflexia in spinal cord injury¶

Autonomic dysreflexia (AD), also called autonomic hyperreflexia, is a life-threatening acute hypertensive medical emergency that affects people with a spinal cord injury (SCI) at or above the sixth thoracic vertebra (T6 level and higher, including all cervical tetraplegia/quadriplegia and high thoracic paraplegia). Triggered by a painful or irritating stimulus below the level of injury, most commonly an overfull bladder, a kinked or blocked urinary catheter, or severe bowel constipation, the lower spinal cord fires an uncontrolled sympathetic reflex that constricts abdominal and leg blood vessels. Blood pressure skyrockets within minutes by 20 to 40 mmHg or more above the person's low baseline (often reaching \(180\text{ to }300\text{ mmHg}\) systolic), causing a sudden pounding headache, profuse sweating above the injury, dangerous heart slowing (bradycardia), seizures, hemorrhagic stroke, retinal hemorrhage, myocardial infarction, and death if the person is not immediately sat upright and the underlying trigger relieved.

Chitani izi tsopano¶

1. Sit the person straight upright at a 90-degree angle and dangle their legs down. If the person is lying in bed, raise the head of the bed to 90 degrees and lower their legs over the side of the mattress; if they are in a reclining power wheelchair, tilt the seat fully upright and lower the leg rests. Gravity causes orthostatic pooling of blood in the paralyzed lower body and provides the fastest non-drug drop in blood pressure.
2. Masulani kapena chotsani zovala zonse zothina, zomangira, zomangira, ndi masitonkeni okanikizira. Nthawi yomweyo masulani zomangira pamimba, zomangira pachifuwa, malamba olimba, zingwe za nsapato, zomangira zikwama zam'miyendo, zotchingira makondomu, ndi thalauza zothina, ndikuvula masitonkeni olimba (TED hose). Kuchotsa kupsinjika kwakunja kumakulitsa mphamvu ya venous ya pamimba ndi miyendo ndikuchotsa zoyambitsa zapakhungu.
3. Yang'anani kuthamanga kwa magazi mphindi 2 mpaka 5 zilizonse ndikuzindikira kutsika kwa SCI. Kupuma kokhazikika kwa kuthamanga kwa magazi kwa munthu yemwe ali ndi khomo lachiberekero kapena chifuwa chachikulu cha thoracic tetraplegia/paraplegia amakhala otsika mwachibadwa, nthawi zambiri \(90\text{ mpaka }110\text{ mmHg}\) mwa akulu. Chifukwa chake, kuthamanga kwa magazi kwa \(120/80\text{mmHg}\) kapena \(130/85\text{mmHg}\) (komwe kumawoneka ngati "zabwinobwino" kwa namwino wosaphunzitsidwa kapena wachipatala) kumayimira koopsa \(20\text{ to }40\text{mmHg}\)$ hypertensive surgeia.
4. Yang'anani chikhodzodzo ndi dongosolo la mkodzo KAYAMBI (zimayambitsa 75 mpaka 85 peresenti ya matenda onse). Ngati munthuyo ali ndi foley kapena suprapubic catheter, fufuzani chubu kuchokera m'thupi kupita ku thumba lotolera nthawi yomweyo: chotsani chubu chilichonse chopotoka, kwezani mikodzo kuti mkodzo utsike pansi, masulani thumba lopanda kanthu. Ngati palibe mkodzo womwe ukuyenderera mu catheter kwa mphindi ziwiri mpaka 3, yambani pang'onopang'ono ndi 10 mpaka 15 milliliters (0.3 mpaka 0.5 madzimadzi ma ounces) a saline wosabala m'chipindamo ngati ataphunzitsidwa (musamakakamize madzimadzi kapena kugwiritsa ntchito madzi ozizira), kapena **chotsani catheter yotsekedwa ndikuyika katheteriya 2% nthawi yomweyo. Ngati munthuyo achita catheterization yapakatikati, tsitsani chikhodzodzo pakalipano.
5. Yang'anani matumbo KACHIWIRI ngati m'chikhodzodzo mulibe kanthu komanso kuthamanga kwa magazi kumakhalabe kokwera (\(>150\text{ mmHg}\) systolic). Fecal impaction (constipation) ndi chifukwa chachiwiri chofala cha autonomic dysreflexia. Imitsani kutulutsa matumbo kapena kukondoweza m'matumbo nthawi yomweyo. Musanayang'ane matumbo ndi chala chotchinga, ngati kuthamanga kwa magazi kuli kudutsa kapena kupitirira \(150\text{mmHg}\)systolic, imbani nambala yanu yazadzidzi (911 ku United States ndi Canada, 112 ku European Union, 999 ku United Kingdom, kapena onani zonse ku United Kingdom, manambala angozi) ndikupatsa wodwalayo mankhwala omwe amamwa mwachangu kapena apakhungu a antihypertensive (monga sublingual/chewed nifedipine, captopril, kapena topical nitroglycerin paste, **pokhapokha atatsimikizira kuti palibe sildenafil/Viagra ntchito **). Dikirani mphindi zisanu mutalowetsa 2% lidocaine wa mankhwala ogonetsa gel mu rectum musanachotse pang'onopang'ono chopondapo kuti musawonjezeke.
6. Check the skin and extremities THIRD, and call 911 / 112 / 999 if symptoms persist or BP stays \(\ge 150\text{ mmHg}\). If both bladder and bowel are clear, inspect below the injury level for hidden pain triggers: sitting on a wallet, phone, catheter valve, or hard wheelchair seam; an ingrown toenail; a pressure ulcer (bedsores); sunburn or scald burn; a hidden leg bone fracture; or menstrual cramping/labor. Call emergency medical services immediately if you cannot find the trigger, if systolic blood pressure stays at or above \(150\text{ mmHg}\), or if a severe pounding headache, vision changes, chest pain, or confusion persists.

Pathophysiology: Chifukwa chiyani T6 ndiye mzere wogawikana wa anatomical¶

Kumvetsetsa chifukwa chake autonomic dysreflexia imachitika pokhapokha kuvulala kwa msana kapena pamwamba pa **T6 (chisanu ndi chimodzi cha thoracic) gawo la msana ** (ndipo nthawi zina T7 mpaka T8) imapangitsa kuti sitepe iliyonse ya ndondomeko yadzidzidzi ikhale yomveka.

1. Kukondoweza kowawa kapena koopsa kumachitika pansi pa kuvulala kwa msana: Ngakhale kuti munthuyo sangamve kupweteka kwa chikhodzodzo chotalikirana kapena chikhadabo cholowera pansi pa zilonda za msana, kupweteka kwam'mutu komanso minyewa yotambasuka m'chikhodzodzo, m'matumbo, kapena pakhungu imanyamulabe chizindikiro chodzidzimutsa kumunsi kwa msana.
2. Massive splanchnic sympathetic outflow (T5 to L2): Chizindikiro cha kupsinjika chikalowa mumsana pansi pa chovulalacho, chimayenda m'mwamba mpaka kukafika pachilonda cha msana / transection. Polephera kudutsa bwino ku ubongo, chizindikirocho chimayambitsa chiwongoladzanja chachikulu, chosagwirizana ndi msana pamtundu wa thoracolumbar sympathetic chain (** T5 kupyolera mu L2 **). Chochititsa chidwi n'chakuti, minyewa yayikulu ya splanchnic imachokera ku T5 kupita ku T9 ** ndikuwongolera ** splanchnic vascular bed ** (mitsempha yayikulu yamagazi m'mimba, matumbo, chiwindi, ndulu, ndi impso zomwe zimagwira pafupifupi ** 25 mpaka 30 peresenti ya kuchuluka kwa magazi m'thupi la munthu **).
3. Chifukwa chiyani T6 ndi pamwambapa zimapanga vuto la kuthamanga kwa magazi: Pamene chotupa chiri pa **T6 kapena kupitirira apo **, zizindikiro zotsika za ubongo (zoletsa) sizingadutse kuvulala kwa msana kuti zifike ku T5 ku T9 splanchnic nerves. Mitsempha ya splanchnic ya magazi ndi minyewa yakumunsi ya thupi imakakamira mwamphamvu, kufinya lita imodzi ya magazi kupita m'chifuwa, khosi, ndi ubongo mkati mwa masekondi pang'ono ndikupangitsa kuthamanga kwa magazi kukwera ndi \(40\text{mpaka}150+\text{mmHg}\). (Mosiyana ndi izi, ngati kuvulala kwa munthu kuli pa T10 kapena L1, ubongo wawo umakhalabe ndi mphamvu pa T5 mpaka T9 splanchnic bed ndipo ukhoza kukulitsa mitsempha ya m'mimba kuti ateteze matenda oopsa).
4. Zododometsa za thupi (Vasoconstriction Pansi, Vasodilation ndi Bradycardia Pamwambapa):
5. Above the injury: Carotid sinus and aortic arch baroreceptors sense the dangerous blood pressure spike and alert the brainstem. The brainstem sends two emergency signals: first, it fires the vagus nerve (Cranial Nerve X), which travels outside the spinal cord directly to the heart to slow the heart rate down (reflex bradycardia, often \(40\text{ to }55\text{ beats per minute}\), though some patients show tachycardia or arrhythmias); second, it dilates blood vessels and activates sweat glands in the intact spinal segments above the level of the injury, causing a throbbing vascular headache, bright red flushed face and neck, profuse forehead/shoulder sweating, and nasal congestion.
6. Below the injury: Because the brainstem's calming signals are blocked at the spinal cord lesion, the lower body remains locked in extreme sympathetic vasoconstriction, appearing pale, cold, clammy, and covered in goosebumps (piloerection).

Recognizing autonomic dysreflexia: Baseline blood pressure vs. crisis numbers¶

One of the deadliest medical errors in emergency rooms occurs when a triage nurse or paramedic measures a quadriplegic patient's blood pressure at \(135/85\text{ mmHg}\), declares "Your blood pressure is completely normal," and ignores a life-threatening autonomic dysreflexia crisis.

Because people with cervical or high thoracic spinal cord injuries lack baseline sympathetic vascular tone, their normal resting blood pressure is neurogenically hypotensive. Use this reference table to interpret blood pressure accurately by age group (based on the Consortium for Spinal Cord Medicine / Paralyzed Veterans of America guidelines):

Classic signs and symptoms above and below the level of injury¶

• Sudden, severe pounding headache (bifrontal or occipital): Feels like a jackhammer inside the skull as cerebral arteries stretch under high pressure.
• Profuse sweating (diaphoresis) above the level of injury: Sweat pours down the forehead, face, neck, and upper shoulders while the lower body stays bone-dry.
• Red blotchy skin flushing (erythema) above the level of injury: Bright red patches across the face, neck, and upper chest.
• Cold, pale, clammy skin and goosebumps (cutis anserina / piloerection) below the level of injury (and sometimes across the arms in high cervical injuries).
• Sudden nasal congestion (stuffy nose): Caused by parasympathetic vasodilation of the nasal mucosa.
• Visual disturbances: Blurred vision, seeing spots (scotomata), or sensitivity to light.
• Cardiac symptoms: A slow, heavy pounding pulse in the neck (bradycardia below 60 beats per minute) or sudden irregular heartbeats, chest tightness, and overwhelming anxiety or a feeling of impending doom.
• "Silent" Autonomic Dysreflexia: Up to 30 to 40 percent of documented blood pressure spikes during urodynamic testing or bowel care occur with minimal or zero headache, meaning caregivers should check blood pressure whenever a patient shows unexplained facial flushing, sweating, or increased muscle spasms (spasticity).

Comprehensive checklist of autonomic dysreflexia triggers (The 3 Bs: Bladder, Bowel, Body)¶

When hunting for the cause of an autonomic dysreflexia episode, never search at random. Work systematically through the Bladder (75% to 85% of all cases), then the Bowel (10% to 15% of cases), and finally the Skin/Body (5% to 10% of cases).

Kuthetsa mwatsatanetsatane catheter yamkodzo popanda kukulitsa vutolo¶

Chifukwa pafupifupi 4 mwa 5 autonomic dysreflexia episodes imachokera ku chikhodzodzo, kudziwa zomwe ** osati ** kuchita ndi catheter ya mkodzo n'kofunika monga kudziwa zoyenera kuchita:
