Review[Robot-assisted surgery in visceral and thoracic surgery gynaecology, urology - importantanaesthetic considerations].
Robot-assisted surgery, as a development of laparoscopic surgery, has an increasing field of application. Beside urology, this technique has also been implemented in visceral and thoracic surgery and gynaecology. For the surgeon an enhanced view of the surgical field and a better mobility of the instruments are the most important advantages. ⋯ Therefore, a standardised order and protection of all i. v.-lines, cables and the ventilation-hose of the (double-lumen) tube is essential. After the roboter is connected to the patient, it is nearly impossible to change or extend patient monitoring. Especially in case of emergency, e. g. respiratory complications or heart failure, a close communication with the surgeon and a team approach are indispensable.

Review[Perioperative management of patients with opioid tolerance and misuse].
Patients with opioid pretreatment can be divided into different groups. While patients after successful drug addiction treatment with or without drug replacement therapy usually not require an extensive perioperative pain therapy, patients with persistent chronic pain and patients with an existing opioid addiction regularly are challenging for the anesthetist. Important pathophysiological issues among the patients include opioid tolerance, opioid-induced hyperalgesia (OIH) as well as acute withdrawal symptomes. ⋯ A similar statement applies to clonidine and dexmedetomidine, which probably induce analgesia by activation of the descending antinociceptive noradrenergic system. The intraoperative administration of S-ketamine is recommended for patients who either already have developed opioid tolerance or suffer from neuropathic pain, and by which postoperative pain is high and was already shown to be poorly adjusted. Other therapeutic options such as intraoperative administration of magnesium or lidocaine may be promising approaches.
