Cell body reorganization in the spinal cord after elective surgery to treat palmar sweating

The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.

Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

significant fall in left circumflex coronary flow was proportional to the decline in external heart work due to sympathectomy

http://www.springerlink.com/content/k2n6j4555g16x773/

sympathectomy affects the heart, sweating, and circulation

heart rate was significantly reduced at rest (14%), at sub-maximal exercise (12.3%), and at peak exercise (5.7%), together with a significant increase in oxygen pulse (11.8, 12.7, and 7.8%, respectively). The rate pressure product (RPP) was also significantly reduced following the surgical procedure at all three study stages, while all other physiological variables measured remained unchanged. It is suggested that thoracic-sympathetic denervation affects the heart, sweating, and circulation of the respective denervated region

Post-sympathectomy neuralgia is a severe complication since pain can be permanent, severe, and incapacitating

http://www.springerlink.com/content/q04711t06j164206/

Possible surgical complications of sympathectomy may include

  • Horner's syndrome
  • Infection
  • Hematoma
  • Bleeding
  • Postsympathectomy neuralgia
  • Pleurotomy
  • Pleural effusion
  • Phrenic nerve injury
  • Subclavian artery injury
  • Adverse reaction to anesthesia
  • Collapsed lung

"ETS has proved moderately successful in treating hyperhidrosis, although the operation does carry a high risk of complications. "

Other complications of ETS include:

  • sweating on the face and neck after eating food (gustatory sweating),
  • inflammation of the nose (rhinitis), and
  • air becoming trapped between the layers of the lung (pneumothorax) which can cause chest pain and breathing difficulties (although this usually resolves itself without the need for treatment).
Rarer complications of ETS include:
  • Horner's syndrome, a condition that causes drooping of the eyelids, and
  • damage to the phrenic nerve (a nerve that is used to help in breathing).
Phrenic nerve damage can lead to shortness of breath, though it may be possible to repair the nerve during surgery.

75% pneumothorax expected after sympathectomy

A small insignificant pneumothorax can be expected after ETS in about 75% of cases [15], which gets spontaneously absorbed, usually within 24 h.

Permanent side effects included compensatory sweating in 67.4%, gustatory sweating in 50.7% and Horner's trias in 2.5%. However, patient satisfaction declined over time, although only 1.5% recurred. This left only 66.7% satisfied, and a 26.7% partially satisfied. Compensatory and gustatory sweating were the most frequently stated reasons for dissatisfaction. Individuals operated for axillary hyperhidrosis without palmar involvement were significantly less satisfied (33.3% and 46.2%, respectively).

sympathectomy improves skin blood flow at the thermoregulatory but not the nutritive level of skin microcirculation

sympathectomy improves skin blood flow at the thermoregulatory but not the nutritive level of skin microcirculation. This may be related to the fact that the thermoregulatory vessels are mainly sympathetically controlled, whereas the nutritive capillaries are mainly controlled by local (nonneural) factors.

Iatrogenic harlequin syndrome resulting from sympathectomy

Postgrad Med J 2003;79:278 doi:10.1136/pmj.79.931.278
A 29 year old man with severe facial hyperhidrosis underwent an uncomplicated right thoracoscopic sympathectomy. Before operating on his left side, a starch-iodine preparation was applied to his face in order to demarcate residual sudomotor function. The preparation becomes blue on exposure to moisture, thereby representing residual sweat gland activity.
Figure 1 demonstrates that sympathetic innervation to the face is strictly unilateral, and nerve fibres do not appear to cross the midline. This is essentially an iatrogenic variation of the harlequin syndrome,2 which usually results from interruption of post-ganglionic sympathetic fibres secondary to malignant invasion.
His facial hyperhidrosis was completely treated once the contralateral sympathectomy was performed.

T3 sympathectomy leads to subclinical pupillary dysfunction with a tendency for miosis

We found statistically significant differences (P < 0.001) between the preoperative P/I ratio [0.40 mm (standard deviation, SD 0.07 mm)] and the postoperative basal ratio [0.33 (SD 0.05)] at 24 h. The P/I ratio at 24 h increased from 0.33 to 0.36 (SD 0.09), a nonsignificant increase (P = 0.45), after instillation of medicated eye drops. No differences were observed between the preoperative [0.40 (SD 0.07)] and 1-month basal values [0.38 (SD 0.07)], and instillation of apraclonidine no longer induced a hypersensitivity response.

CONCLUSIONS:

T3 sympathectomy leads to subclinical pupillary dysfunction with a tendency for miosis, even though this impairment is not generally evident on standard physical examination or reported by patients. This subclinical dysfunction may be caused by injury to an undefined group of presympathetic nerve cell axons in caudocranial direction that communicate with the cervical sympathetic ganglia and whose function is mydriatic pupillary innervation.

medical students need to realise how vulnerable they are to being seduced by the special privileges of their profession

More than 7% of all German physicians became members of the Nazi SS during World War II, compared with less than 1% of the general population. In so doing, these doctors willingly participated in genocide, something that should have been antithetical to the values of their chosen profession. The participation of physicians in torture and murder both before and after World War II is a disturbing legacy seldom discussed in medical school, and underrecognised in contemporary medicine. Is there something inherent in being a physician that promotes a transition from healer to murderer? With this historical background in mind, the author, a medical student, defines and reflects upon moral vulnerabilities still endemic to contemporary medical culture.
http://jme.bmj.com/content/early/2012/05/02/medethics-2011-100372.abstract

Alessandra Colaianni, of Johns Hopkins Medical School, asks the unsettling question: "Is there something inherent in being a physician that promotes a transition from healer to murderer?" Some recent situations in the United States suggest that this is possible: allegations of euthanasia in the wake of Hurricane Katrina, torture of Guantanamo detainees, and the participation of doctors in capital punishment. Colaianni suggests that there are illuminating parallels between medical training and the work of doctors in Auschwitz.
Socialisation and hierarchy: doctors are pressured to conform to group norms, often with techniques like "Sleep deprivation, heightened stress levels and fear of failure". Ambition: just as Nazi doctors participated in the T4 euthanasia program to advance their careers, today's doctors are pressured to succeed even at the risk of losing their integrity. Doctors have a "licence to sin" which can easily be perverted: some "actions are allowed when they are performed by physicians, but are the stuff of horror films and criminal cases when non-licensed personnel attempt them."
Detachment was also a characteristic of Nazi doctors. They could select prisoners by day and dine with their colleagues by night: "the medical profession requires unflappability in the face of things that others would consider disgusting, horrific, or otherwise overwhelming".
Colaianni concludes that medical students need to realise how vulnerable they are to being seduced by the special privileges of their profession. "It is for this reason that a solid grounding in principles of ethics, individualism and human rights is so crucial for physicians and others in positions of power or trust."

nerves that sent blood-pressure-raising flight-or-fight signals to the brain were cut

page 187:
It was a grueling operation called sympathectomy, in which the nerves that sent blood-pressure-raising flight-or-fight signals to the brain were cut...The nerve cutting scrambled signals to her circulatory system. She was cold on one side of her body and warm on the other.

The second thoracic sympathetic ganglion was most commonly located (50%) in the second intercostal space

Presence of the stellate ganglion was noted in 56 (84.8%) sides, and 6 (9.1%) sides showed a single large ganglion formed by the stellate and the second thoracic sympathetic ganglia. The second thoracic sympathetic ganglion was most commonly located (50%) in the second intercostal space. CONCLUSION: The anatomic variations of the intrathoracic nerve of Kuntz and the second thoracic
sympathetic ganglion were characterized in human cadavers.
