This article describes the history of pain therapy and anesthesiology with respect to the field of surgery. The history of this part of medicine is dependent upon the development of the appropriate medication groups, which were of great importance in the field of pain therapy and anesthesiology. ⋯ The above mentioned developments combined with the knowledge of physiology of pain and new results from psychological studies led to the modern pain therapy in recent perioperative treatment concepts. Modern pain therapy is a multimodal therapy concept with a variety of specialties working as a team to optimize an individualized therapy plan which respects the needs of every single patient under different circumstances (acute, perioperative and chronic pain).

Pain therapy after surgical procedures of the lower extremity is an important goal, whereas insufficient analgesia leads to an essential reduction of the patient's mobility and convalescence. If possible, regional anaesthetic and intrathecal procedures for pre-, intra- and postoperative analgesia should be used. Systemic analgesics should not be used preoperatively, whereas non-opioids and opioids are recommended postoperatively. ⋯ There is no scientific rationale as an argument for inserting drains. The surgical approach depends more on the individual patient's anatomical characteristics. Whereas the regional analgesic regimen is more effective than systemic therapy, sufficient tools for pain reduction during surgical procedures of the lower extremity are at the orthopaedic surgeon's disposal, too.

A dorsal approach during spinal surgery offers the possibility to distribute drugs directly to the nerve root or epidurally. This can be done via a single intraoperative dose or by placing an epidural catheter. A safe and effective analgesia can thereby be achieved. ⋯ Here the local application of local anesthetics or opioids makes sense. In transthoracic approaches epidural analgesia is recommended by thoracic surgeons, but this is difficult to perform especially in children with deformities. Furthermore it is generally important not to compromise neuralgic controls by analgesic measures.

Comparative Study
[New and evidence-based aspects of postoperative pain therapy].
Poorly managed postoperative pain has been recognised to delay patient recovery and hospital discharge. Recent metaanalyses support a multimodal approach with combinations of analgesics from different classes. ⋯ Local, intraarticular, epidural, and, more importantly, modern peripheral regional techniques can be used successfully to enhance perioperative analgesia. The use of continuous perineural techniques with local anaesthetic infusion has been extended beyond hospital discharge in many European countries.

Orthopaedic and traumatized patients often suffer from severe pain after surgery or trauma. Their early recovery also depends on an efficient acute pain relief based on a combination of systemic medication, local drug application and physical therapy. In 2007, new guidelines for the treatment of perioperative and traumatic pain were published. ⋯ It is helpful to establish an acute pain service for daily rounds and documentation. The individual patient should be informed about his specific acute pain therapy before the operation. Pain scores should be frequently documented by the patient.
