To retrospectively test the actual need for sedatives and opioids when cranial nerve blocks and specific therapeutic communication are applied.
In a case series, 64 consecutive patients Zech et al. from University Hospital Regensburg, treated with a strong rapport, constant contact, non-verbal communication and hypnotic suggestions, such as dissociation to a “safe place,” reframing of disturbing noises and self-confirmation, and compared to 22 preceding patients under standard general anesthesia or conscious sedation.
With introduction of the protocol the need for sedation dropped from 100% in the control group to 5%, and from a mean dose of 444 mg to 40 mg in 3 patients. Remifentanil originally used in 100% of the patients in an average dose of 813 µg was reduced in the study group to 104 µg in 31% of patients. There were no haemodynamic reactions indicative of stress during incision, trepanation, electrode insertion and closure.
With adequate therapeutic communication, patients do not require sedation and no or only low-dose opioid treatment during DBS surgery, leaving patients fully awake and competent during surgery and testing 1)1) Zech N, Seemann M, Seyfried TF, Lange M, Schlaier J, Hansen E.
