History of anesthesia for ambulatory surgery

2020

According to the definition of the International Association for the Study of Pain (IASP), pain is defined as: "Unpleasant subjective feeling and emotional experience associated with current or potential tissue damage of a particular localisation", which, as such, poses a challenge for epidemiological research to determine its frequency and prevalence. We have all heard the motto that surgery has experienced its unprecedented development on the wings of anaesthesia. This is most certainly the case, since it is precisely the pain that prevents any invasive procedure on the human body, hence the very elimination of pain has opened up the way for the application and development of surgery. For this reason, the skill and now the science of anaesthesia are epochal civilizational achievements, which is why it is worth remembering the attempts and successes of its application. The very beginning of mankind cannot be imagined without the humans facing some sort of pain. As long ag...

Ambulatory Surgery, 2003

The aim of this study was to evaluate the incidence of side effects and their relation with anesthetic techniques in patient undergoing ambulatory surgery. 654 patients, ASA I Á/II, aged between 20 and 70 years scheduled for ambulatory surgery were enrolled into the study protocol. Patients were requested to record the existence of headache, sore throat, postoperative pain, nausea, vomiting, muscle weakness, lack of appetite, drowsiness, sleep disturbances, dizziness, dysuria, and lumbar pain during first week postoperatively. Postoperative pain was significantly higher after peripheral neural blockage. Muscle weakness, sore throat, lack of appetite, dysuria, sleep disturbances, headache, and dizziness were significantly higher after inhalational anesthesia (P B/ 0.05). It was concluded that total intravenous anesthesia or neural blockade should be preferred for ambulatory surgery and an effective postoperative analgesic therapy should be planned before discharge. #

The anesthesiology profession may one day serve as a cautionary tale of how power, politics and privilege can perturb science and progress. Previous anesthesia practitioners possessed a superior understanding of physiology and pharmacology, but overenthusiastic CO2 supplementation with inadequate monitors and machines caused asphyxiation disasters that were improperly attributed to CO2 toxicity. Dr. Ralph Waters founded the anesthesiology profession on the basis of a practical new anesthetic tech- nique that introduced elective intubation and hyperventilation to eliminate CO2 toxicity, but mechanical hyperventilation dangerously depletes CO2 tissue reserves and exag- gerates morbidity and mortality. The bene ts of CO2 supplementation were forgotten, and consequent CO2 confusion has derailed research, discouraged opioid treatment, damaged patient safety, and disrupted professional progress. Anesthesiologists can no longer claim to provide superior service, and hospital administrators are replacing them with nurses. Professional membership is in decline, and professional survival is in ques- tion. Modern machines have eliminated asphyxiation, and modern monitoring enables safe and bene cial hypercarbia that complements opioid treatment and minimizes sur- gical morbidity and mortality. CO2 reform promises revolutionary advance but faces formidable opposition.

Increasingly, we are being asked to provide anesthesia or heavy sedation for patients undergoing procedures outside of the operating room. This represents a clinical, staffing, and financial challenge to most anesthesiology departments. While provision of anesthesia services within an operating room environment has been associated with increasing safety over the past several decades, settings outside of the operating room may present unique challenges. For these reasons, it is important the Anesthesiology Clinics address this important topic. In this issue, three major areas of care are addressed: financial implications, optimal care paradigms for specific patients, and locations and priorities with respect to all out-of-operating-room settings.

Today, an increasing number of diagnostic and therapeutic procedures are performed in specialized units outside the classical operating room, such as endoscopy units, interventional radiology, neurology and cardiology laboratories. The main reasons of this global trend are recent advances in medical technology, increased knowledge of disease pathogenesis, and some financial factors. Additionally, number and complexity of these procedures are rapidly raising throughout the world. In parallel, the importance of anesthesia management of such patients, also known as non-operating room anesthesia, has become better understood in recent years. In this review, we aimed to discuss the potential difficulties of non-operating room anesthesia, preprosedural patient preparation, intraoperative anesthesia applications, and postprosedural patient care in the light of the current literature.

Canadian Journal of Anaesthesia-journal Canadien D Anesthesie, 1986

This paper describes the outcome of a nine-year post-anaesthetic followup program in a large teaching hospital (N = 112,721 anaesthetics). Between time periods 1975-78 and 1979-83, more seriously ill patients (higher ASA physical status) were being treated. Anaesthetic practice also changed, with an increased use of balanced (multiple drug) anaesthetic procedures, a decrease in the use of halothane and an increase in the use of monitoring. Nonfatal anaesthetic complications — intraoperative, recovery room and postoperative — were rare but there was an increase in the reported complication rate over time. From 1975-78, 7.6per cent of all cases had at least one intraoperative complication and from 1979-83, this rose to 10.6 per cent of all cases. For recovery room complications, there was an increase to5.9 per cent in 1979-83 from 3.1 per cent in 1975-78. In time period 2 there was a 9.4 per cent chance of having a postoperative anaesthetic-related complication, and a 0.45 per cent chance of a significant morbidity as a result. This represents an increase over time period 1 (8.9 and 0.40 per cent respectively). It is concluded that the anaesthetic experience, while associated with low mortality rates in recent years, is still associated with significant morbidity. It is conjectural at present whether this is refiective of preoperative patient status, anaesthetic practice, or other undefined variables associated with an operative experience. Ce papier expose les résultats de neuf ans d’étude d’un programme de suivie post-anesthésique dans un grand hôpital universitaire (N = 112,721 anesthésies). Pour les périodes de 1975-78 et 1979-83 plus de patients sérieusement malades (classe ASA plus élevés) ont été traités. La pratique anesthésique a aussi changé avec un accroissement dans l’utilisation d’une anesthésie balançée (l’utilisation de plusieurs drogues) la diminution dans l’utilisation de l’halothane et une augmentation dans l’utilisation des moniteurs physiologiques. Les complications anesthésiques non léthales pour les périodes per-opératoire, en salle de réveil et en période post-opératoire étaient rares. Cependant on a observé un accroissement dans le taux de complications rapporté à travers le temps. Pour la période de 1975-78, une complication per-opératoire a été rapportée pour 7,6 pour cent des cas. De 1979-83, ce pourcentage augmenta à 10.6 pour cent. Pour les complications survenant à la salle de réveil on observa un accroissement de 5.9 pour cent en 1979-83 à partir de 3.1 pour cent en 1975-78. Dans la deuxième période étudiée le risque d’avoir des complications post-opératoire reliées à l’anesthésie était de 9.4 pour cent avec 0.45 pour cent de risque d’avoir une morbidité significative. Ceci représente un accroissement par rapport à la première période de 8.9 et 0.40 pour cent respectivement. On conclut que l’expérience anesthésique même si elle est associée avec un taux de mortalité bas dans les dernières années reste pour le moins encore associée avec une morbidité significative. Il est hypothétique actuellement de penser que ceci peut être le reflet de l’état pré-opératoire du patient, de la pratique anesthésique ou tout autre variable indéfinie associée avec une expérience chiruricale.

Mending Bodies, Saving Souls: A History of Hospitals, 1999

This chapter depicts the “discovery” of ether anesthesia at the Massachusetts General Hospital within the context of Boston medicine, surgery and dentistry, discussing the local struggles for professional and cultural identity within an environment of sectarianism and professional secrecy. For this purpose, the narrative uses the story of Alice Mohan who actually became the first patient submitting to full ether inhalation for the amputation of her right leg. Mohan’s successful major surgery, performed on November 7, 1846, followed a prior, famous but brief attempt to remove Gilbert Abbott’s congenital neck tumor that forever put Boston and America on the list of pioneering surgical achievements. More than Abbott’s case, Mohan’s long pre-operative hospitalization and botched treatments provide a rare view into the state of contemporary medical therapeutics and the evolution of the Massachusetts General Hospital.

A randomized double‑blind study to evaluate efficacy and safety of epidural magnesium sulfate and clonidine as adjuvants to bupivacaine for postthoracotomy pain relief Abstract Background: The aim of the study was to compare postoperative pain relief in patients undergoing an elective thoracotomy with thoracic epidural analgesia using single shot magnesium and clonidine as adjuvants to bupivacaine. Methods: In a randomized prospective study, 60 patients of American Society of Anesthesiologists physical status I–III of either sex, between 20 and 60 years undergoing elective unilateral thoracotomy, were allocated to three equal groups of 20 patients. Each patient received thoracic epidural analgesia using bupivacaine alone (Group A) or with magnesium (Group B) or clonidine (Group C) at the end of surgery during skin closure. Postoperatively, pain was measured using a visual analog scale (VAS). Rescue analgesia (50 mg tramadol intravenous) was given at a VAS score of ≥4. Duration of analgesia and total dose of rescue analgesic during 24 h was calculated. Postoperative sedation and other side effects if any were recorded. Results: All the groups were homogeneous with respect to their demographics. The 24 h cumulative mean VAS score in Groups A, B, and C was 3.12 ± 0.97, 2.86 ± 0.43, and 1.83 ± 0.59, respectively. The duration of analgesia was prolonged in Group C (165 ± 49.15 min), followed by Group B (138 ± 24.6 min), and Group A (118.5 ± 52.8 min). The duration of analgesia was significantly prolonged in the clonidine group as compared to the control group (P = 0.001). The number of rescue analgesia doses were more in Group A (3.3 ± 1.65) followed by Group B (2.35 ± 0.98) and Group C (1.75 ± 0.71). The sedation scores were significantly higher in Group C. However, shivering was seen in Group A (40%) and Group C (20%) and absent in Group B (P = 0.003). Conclusion: Thoracic epidural analgesia using bupivacaine with clonidine is an efficient therapeutic modality for postthoracotomy pain. Magnesium as an adjuvant provided quality postoperative analgesia decreasing the need for postoperative rescue analgesia and incidence of postoperative shivering without causing sedation.
