Management of Severe Paroxysmal Sympathetic Hyperactivity Following Hypoxic Brain Injury

Clonidine for sedation in infants during therapeutic hypothermia with neonatal encephalopathy: pilot study

OBJECTIVE

To determine a safe dose of clonidine (CLON) to be used in infants with hypoxic ischemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH).

STUDY DESIGN

A pilot prospective study was performed to determine the effect of CLON on autonomic parameters, the pharmacokinetics (PK) of CLON, and the amount of morphine (MOR) given "as needed" for shivering and agitation in a cohort of infants (n = 12) with HIE undergoing TH compared to a historical control group (n = 28).

RESULTS

The CLON group received less "as needed" MOR than the MOR-only group for agitation/shivering (p < 0.001), and the CLON vs. MOR-only group spent 92% vs. 79% of cooling time at the target core body temperature (CBT; p = 0.03, CLON vs. MOR).

CONCLUSIONS

Intravenous CLON (1 mcg/kg Q8h) is well tolerated in infants treated with TH for HIE. CLON stabilizes CBT in the ideal range during cooling, which may be optimal for neuroprotection.

Evaluation of general anesthesia and sedation during dental treatment in patients with special needs: A retrospective study

Background

Patients with special health care needs are more likely to develop health problems, including dental problems. Dental treatments require a good level of communication with the patient. Therefore, in these patients, sedation and general anesthesia are an extremely humanistic approach for comfortable and successful treatment. In patients with special needs, there is no standard anesthetic approach due to varying clinical conditions. The aim of this study was to provide literature content about the anesthetic approaches used by us in patients with special needs.

Methods

The medical records of 710 patients with special health care needs treated under general anesthesia or sedation were reviewed retrospectively. Demographic data, the American Society of Anesthesiologists classification, Mallampati score, anesthesia duration, anesthesia type, anesthetic and analgesic agents used, dental treatment performed, secondary diseases, and complications in the perioperative period were recorded. Patients were evaluated under five groups: Down syndrome, other syndromes, psychiatric disorders, physical disabilities, and complicated medical story.

Results

Among the patients evaluated, 47.5% were females and 52.5% were males (mean age 15.76 ± 11.17 years), and general anesthesia and sedation were administered in 72.9% and 22.1% patients, respectively. The mean duration of anesthesia was 43.20 ± 35.85 min. Simple dental treatments were performed in all groups, and the most common complications were observed in the other syndromes group.

Conclusion

Complications can be reduced by utilizing the appropriate anesthetic approach and taking serious precautions in patients with special needs.
