Comparative Study
[Postoperative pain management after minimally invasive hysterectomy : Thoracic epidural analgesia versus intravenous patient-controlled analgesia.]
In view of the development of innovative and non-traumatic surgical techniques, postoperative pain management should be carried out depending on the invasiveness of the intervention. In the present study two analgesic strategies were compared in patients undergoing minimally invasive hysterectomy: epidural analgesia (EDA) and intravenous patient-controlled analgesia (iv-PCA). ⋯ To reduce the number of patients suffering from postoperative pain a procedure-specific pain management should be developed. The results of this study have shown that even in minimally invasive surgery, such as vaginal hysterectomy and laparoscopically assisted vaginal hysterectomy there are some advantages for epidural analgesia compared to intravenous patient-controlled analgesia. In particular reduced pain intensity, lower need for analgesics and reduced occurrence of PONV can lead to excellent patient comfort, fast recovery as well as positive effects on health-related quality of life. However, there are also some disadvantages such as an increased rate of urinary retention and restriction of mobility.

Resection of the esophagus is an invasive 2-cavitiy procedure which requires special anesthesiological expertise during perioperative care. Furthermore, in surgery new minimally invasive techniques are continually being established which place special challenges on the treatment team because the anesthesiologist is decisively involved in the course of surgery. ⋯ Minimally invasive esophagectomy with transoral anastomization appears to be an enrichment of the minimally invasive spectrum as interdisciplinary cooperation leads to reduced operation time and a more efficient process of anastomization. This also results in decreased one-lung ventilation time which is directly correlated to postoperative pulmonary complications. In particular, the interdisciplinary character of this technique and the necessity for targeted communication proved to be of assistance also in other situations.

Pre-existing or chronic pain is a relevant risk factor for severe postoperative pain. The prevalence of pre-existing and chronic pain in hospital depends on the time definition used and is approximately 44 % and 33%, at 3 or 6 months, respectively. The aim of this study was to determine the prevalence and importance of pre-existing pain in patients treated by a postoperative acute pain service (APS) and to evaluate the requirements for treatment and resources as well as its quality in this context. ⋯ Pre-existing pain is a common comorbidity in surgery patients treated by the APS. There were no significant differences in treatment requirements and quality of care between the patients. This is in contrast to other studies of postoperative pain management which showed that patients with pre-existing postoperative pain had higher pain intensity. This indicates indirectly that the presence of pre-existing pain should be further evaluated as a potentially useful indication for the support by an APS. However there is an urgent need for further studies to clarify whether this indirect effect can be replicated at other hospitals or in other patient collectives. Also it has to be clarified what benefits pain patients have from this kind of treatment: if they benefit from the APS in general or from the special technique, if there is a long-term effect lasting beyond treatment in the APS or if this group of patients would benefit in general from multiprofessional and non-invasive concepts of acute pain treatment.

Case Reports
[Traumatic dissection of the carotid artery : Challenges for diagnostics and therapy illustrated by a case example.]
Traumatic dissection of the carotid artery is an easily overlooked consequence of trauma with notable morbidity and mortality which can be observed in up to 4% of cases involving multiple trauma. Certain mechanisms and patterns of injury as well as specific symptoms should serve as indicators of a dissection and should therefore result in further diagnostic measures. An early diagnosis is of major relevance. This report describes the case of a 45-year-old victim of a traffic accident who showed symptoms of a dissection which had initially not been diagnosed.
