Background and goals of the study : though rapid detoxification with naloxone (N) seems to be effective in opioid physical dependency treatment [1], some reports suggested caution due to N algogenic and direct vasoconstrictor activity [2]. We tried to prevent N side effects with Na-ATP – preparation of purinergic agonist adenosine, known as systemic analgetic and potent vasodilator [3].

Material and methods : 45 heroin overdosage patients, aged 16–46, were admitted to the ICU with severe hypoventilation (mean PETCO2 67 ± 5 mm Hg). Under standard monitoring (ECG, NIBP, SpO 2 ) tracheal tube, cava- and urinary catheters were placed in all cases. In the first 10 patients Swan-Ganz catheter was inserted to assess PWP, CI, PVR and SVR. With institutional approval, Na-ATP infusion (25.3 ± 4.7 mkg kg–1 min–1) began 20 min before N infusion (1.4 ± 0.8 mkg kg –1 min–1, up to the total dose of 226 ± 30 mkg kg–1) and terminated 1 h after N infusion had finished. Neuromuscular block was performed with pipecuronium (mean 2.5 ± 0.8 mg kg–1 h–1, providing TOF level below 15%). CMV ventilation with nitrous oxide + oxygen 2:1 mixture during all the procedure was adjusted to reach PETCO2 32–36 mm Hg.

Results : No patient demonstrated HR, MAP, CI, PVR or SVR shifts exceeding 20% above or below the base level. PWP never exceeded 15 mm Hg, PVR poor correlated with N infusion rate (P=0.47) and significantly depended on Na-ATP infusion rate (r2 =0.45, P=0.006). Diuresis in all the patients was >1 ml kg–1 h–1. Mean time interval between detoxification completion and extubation was 65 ± 12 min, ICU bed day averaged 2.2 ± 0.5. No complication which could be contributed to N or Na-ATP administration was observed. Post-detoxification abstinent diarrhea in 32 patients was effectively controlled by loperamide (2–4 mg p.o.).

Conclusion: continuous Na-ATP infusion effectively protects heroin addicts against stress-related and hemodynamic complications during rapid naloxone detoxification procedure.
