[Victory over surgical pain : 170 years ago the era of modern anesthesia began - but what happened in the operating theater in the time before?]
170 years ago, on 6 October 1846, the dentist William Thomas Green Morton, sucessfully demonstrated ether anesthesia in a patient undergoing surgery in the operating theater of the Massachusetts General Hospital in Boston. He thereby put an end to the unthinkable suffering of patients who had to undergo surgery when fully conscious. Before this "discovery" surgical procedures resembled a battle for life and death. ⋯ In her diaries and letters, the english novelist Frances Burney described her mastectomy without anesthesia on 30 September 1811. The Scottish physician and novelist John Brown, in his story of "Rab and his friends", painted a picture of the mastectomy of Ailie Noble by the famous Scottish surgeon James Syme in 1833, also without anesthesia. Finally, in his letters the Scottish scientist George Wilson described the amputation of his left foot at the ankle in January 1843, again by James Syme and again without the use of anesthesia.

[Hereditary heterozygous factor VII deficiency in patients undergoing surgery : Clinical relevance].
A hereditary deficiency in coagulation factor VII (FVII) may affect the international normalized ratio (INR) value. However, FVII deficiency is occasionally associated with a tendency to bleed spontaneously. We hypothesized that perioperative substitution with coagulation factor concentrates might not be indicated in most patients. ⋯ Preoperative substitution using coagulation factor concentrates does not seem to be mandatory in patients with an FVII level ≥15 %. For decision-making on preoperative substitution, patient history of an increased tendency to bleed may be more important than the FVII level or increased INR value.

Decompression of the chest is a life-saving invasive procedure for tension pneumothorax, trauma-associated cardiopulmonary resuscitation or massive haematopneumothorax that every emergency physician or intensivist must master. Particularly in the preclinical setting, indication must be restricted to urgent cases, but in these cases chest decompression must be executed without delay, even in subpar circumstances. The methods available are needle decompression or thoracentesis via mini-thoracotomy with or without insertion of a chest tube in the midclavicular line of the 2nd/3rd intercostal space (Monaldi-position) or in the anterior to mid-axillary line of the 4th/5th intercostal space (Bülau-position). ⋯ In extremely urgent cases opening the pleural membrane by thoracostomy without inserting a chest tube is sufficient in mechanically ventilated patients. Complications are common and mainly include ectopic positions, which can jeopardise effectiveness of the procedure, sometimes fatal injuries to adjacent intrathoracic or - in case of too inferior placement - intraabdominal organs as well as haemorrhage or infections. By respecting the basic rules for safe chest decompression many of these complications should be avoidable.

Delirium is a common complication in critical care. The syndrome is often underestimated due to its potentially no less dangerous course as a hypoactive delirium. Therefore, current guidelines ask for a structured, regular and routine screening in all intensive care units. If delirium is diagnosed, symptomatic therapy should be initiated promptly. ⋯ For the first time, this study documents knowledge and implementation of the German S3 guidelines for delirium in intensive care. Overall, the guidelines for delirium care are less well executed than those for sedation. With growing knowledge of the guidelines, diagnosis and treatment of delirium fits the guidelines more frequently. The facility to document a delirium score in intensive records is insufficient. Especially a nursing-based delirium strategy could possibly improve implementation of the guidelines, claiming an eight-hour screening and documentation. However, the small number of hospitals that have integrated the guidelines into in-house standard operating procedures (40 %) shows urgent need for optimization. A re-evaluation involving all relevant caretakers could probably improve the implementation of guidelines in intensive care and perioperative medicine.

[History of anesthesia : "From narcosis to perioperative homeostasis"].
In the western World 16 October 1846 is often called "Ether Day", marking the beginning of anesthesia. Before that date, for physicians there was only a struggle against pain. In the following 170 years all fields of general anesthesia as well as regional and local anesthesia were continuously developed. ⋯ The complexity of this field of medicine requires a specialist: the anesthesiologist, whose selection of the most suitable form of anesthesia for the patient makes the surgical intervention painless. In addition, the history of anesthesia was characterized by personalities who were responsible for the progress of this medical field. Anesthesia is one part of the discipline of anesthesiology, which also includes resuscitation, intensive care medicine, emergency medicine and pain therapy.
