Effective use of blood in elective surgical procedures.

The preoperative requests for crossmatching of blood in elective surgical procedures were studied at the Flinders Medical Centre, South Australia. The study revealed that surgeons order crossmatched blood on the basis of habit. This led to considerable time-expiry of blood, and to unnecessary use of laboratory personnel's time and reagents. The statistical information collected during the study was used to educate the surgeons to change their blood-ordering practice. In procedures where excessive blood loss is unlikely to occur, as a stand-by, a "group-and-screen" procedure was substituted for crossmatching. A firm recommendation for maximum blood order in elective surgical procedures was also made. It is estimated that this approach would save approximately $80,000 per year per 350-bed general hospital in Australia.

A guideline for anticipated blood usage during elective surgical procedures.

A realistic guideline for transfusion therapy was prepared, with the cooperation of the departments of anesthesiology and surgery, in order to reduce excessive crossmatching. The guideline recommends an ABO-Rh type and an antibody screen, instead of the ""routine'' two-unit crossmatch, for elective surgical procedures where blood is seldom used. For those operations normally necessitating hemotherapy, the number of units suggested for the preoperative crossmatch was determined by examination of the average number of units transfused in the past for that particular procedure. The guideline provides the anesthesiologic and surgical staff with the knowledge of how much blood was usually used during a particular elective surgical procedure and therefore how much blood should be preoperatively crossmatched for that procedure. Implementation of this guideline allows the blood bank to distribute its limited blood resources more efficiently and also decreases patient and laboratory costs.

Understanding postoperative fatigue.

Performance characteristics of the central nervous, cardiovascular, respiratory and muscular systems in man postoperatively have received little investigative attention, despite the well known syndrome of postoperative fatigue. The impairmen in perception and psychomotor skills that has been shown to result from caloric restriction, bedrest, sedation and sleep deprivation suggests that a similar deficit may occur after surgical procedures. After a simple elective surgical procedure, maximal oxygen uptake decreases and the adaptability of heart rate to submaximal workloads is impaired. Similar deleterious effects on cardiorespiratory performance have been documented with starvation and bedrest; an understanding of cardiorespiratory performance postoperatively awaits further investigation. Maximal muscular force of contraction is also impaired by caloric restriction and bedrest, suggesting that similar effects may be seen in the postoperative state, although this has not been studied. A better understanding of the syndrome of postoperative fatigue could be achieved by a descriptive analysis of physiologic performance postoperatively. Such descriptive data could form the basis for objective evaluation of therapeutic measures intended to improve performance, such as nutritional supplementation and pharmacologic intervention. The observation that exercise with the patient in the supine position may decrease the impairment in maximal aerobic power otherwise expected in immobilized patients suggests that controlled exercise therapy may be of value in reducing physiologic impairment postoperatively.

Preoperative testing for fecal occult blood: a questionable practice.

The benefit of fecal occult blood testing (FOBT) in patients without gastrointestinal symptoms who are hospitalized for an elective surgical procedure is uncertain. To resolve this issue, we analyzed the costs and benefits of preoperative FOBT by the model of a decision tree. In 2- and 3-way sensitivity analyses, the costs of diagnostic and therapeutic procedures and the probabilities of their various outcomes are varied simultaneously so that we might study their joint influence on the outcome of the decision analysis. The decision analysis shows that preoperative FOBT is associated with a smaller benefit than would be its omission. The higher cost and lower net benefit of preoperative FOBT reflect the impact of false-positive tests for occult blood. False-positive FOBT leads to expenditures for negative gastrointestinal work-ups, increased procedural costs, and a diminished rate of success for the elective surgical procedure, by delaying it. This outcome of the analysis is insensitive to large variations in the costs and probabilities built into the model. We conclude that screening for fecal occult blood provides no benefit if done routinely in patients who are hospitalized for any major surgical procedure.

An analysis of surgical blood use in United States hospitals with application to the maximum surgical blood order schedule.

Excessive preoperative crossmatching can be limited with a maximum surgical blood order schedule (MSBOS) which is a list of the commonly performed elective surgical procedures performed in a hospital with the maximum number of units of blood which will be crossmatched preoperatively for each. The purpose of this study was to analyze the blood requirements of 535,031 surgical patients treated in 300 United States hospitals during 1974, and to suggest maximum preoperative blood orders including type and screen recommendations based on data derived from this large national patient sample. Such recommendations are offered for 63 common elective surgical procedures. Specific reference is made to blood utilization during hysterectomy, transurethral resection of the prostate, and cesarean section. A preoperative type and screen order is adequate for the vast majority of patients undergoing these latter procedures.

Effects of Esketamine on Postoperative Hospital Anxiety and Depression Scale Scores in Patients Undergoing Laparoscopic Radical Resection for Colorectal Cancer.

OBJECTIVE: To investigate the effects of intravenous esketamine on postoperative Hospital Anxiety and Depression Scale (HADS) scores in patients undergoing laparoscopic radical resection for colorectal cancer. METHODS: In this prospective, randomized, placebo-controlled study, adult patients for elective laparoscopic radical resection were randomly assigned (1:1) to a control group (group C) or an esketamine group (group PE). Group C received conventional general anesthesia and patient-controlled intravenous analgesia (PCIA). In group PE, esketamine 0.5&#x2009;mg/kg was injected during induction of anesthesia, with esketamine 1&#x2009;mg/kg added to PCIA. Primary outcome was HADS score on postoperative day 1. Secondary outcomes included HADS scores on postoperative days 3 and 7, sleep quality scores, postoperative level of consciousness, complication rate, length of hospital stay, 24&#x2009;h inflammatory factors, and satisfaction scores. RESULTS: Group PE showed significantly lower HADS-A and HADS-D scores on postoperative days 1 and 3 , reduced 24&#x2009;h interleukin-6 (IL-6) leveland higher patient satisfaction compared with group C (all p&#x2009;<&#x2009;0.05). CONCLUSIONS: Esketamine given during induction and in PCIA reduced early-stage postoperative HADS scores and improved patient satisfaction in colorectal cancer patients.

Impact of a multimodal prehabilitation program on postoperative cognitive dysfunction: a single-center randomized controlled trial.

BACKGROUND: Postoperative cognitive dysfunction (POCD) is a frequent complication after cardiac surgery. Exercise-based prehabilitation may enhance functional reserve and reduce vulnerability to perioperative cerebral insults. We hypothesized that multimodal prehabilitation reduces POCD 3&#xa0;months after cardiac surgery. METHODS: This prespecified substudy of a single-center randomized controlled trial (NCT03466606) included patients aged &#x2265;50&#xa0;years undergoing elective coronary artery bypass grafting and/or valve surgery. Participants were randomized 1:1 to 4-6&#xa0;weeks of multimodal prehabilitation (exercise training, nutritional support, and psychological support) or standard preoperative care. Cognitive function was assessed at baseline and 3&#xa0;months postoperatively using an age- and education-adjusted neuropsychological battery. POCD was defined as performance &#x2265;1.5 standard deviations below normative values in at least 2 cognitive tests, excluding the Mini-Mental State Examination. Logistic regression analyses were performed to evaluate factors associated with POCD. RESULTS: Of 160 participants screened from the parent trial, 134 met eligibility criteria for the substudy and were randomized; 116 completed 3-month follow-up (prehabilitation n&#xa0;=&#xa0;53; control n&#xa0;=&#xa0;63). POCD occurred in 29 patients (25%), including 15/53 (28%) in the prehabilitation group and 14/63 (22%) in controls (odds ratio [OR] 1.37, 95% confidence interval [CI] 0.54-3.50, P&#xa0;=&#xa0;0.52). In multivariable analysis, preoperative cognitive impairment was independently associated with POCD (OR 13.28, 95% CI 4.06-43.41, P&#xa0;<&#xa0;0.001), whereas prehabilitation was not (OR 1.09, 95% CI 0.35-3.45, P&#xa0;=&#xa0;0.877). Higher physical activity levels at 3&#xa0;months were associated with lower odds of POCD (OR 0.97, 95% CI 0.95-1.00, P&#xa0;=&#xa0;0.047). CONCLUSIONS: In this randomized controlled trial, a 4-6-week multimodal prehabilitation program did not reduce postoperative cognitive dysfunction 3&#xa0;months after cardiac surgery. Although the intervention did not achieve measurable cognitive protection, the observed association between postoperative physical activity levels and postoperative cognitive dysfunction warrants further investigation.

Iatrogenic factors in acute renal failure: can vigilance equal avoidance?

Physicians can aid substantially in reducing morbidity and mortality from acute renal failure by exercising particular care when using potentially nephrotoxic procedures or agents, by identifying patients at high risk before undertaking elective surgical procedures, and by acting promptly to correct predisposing conditions.

Glove perforation during surgery: what are the risks?

Surgical gloves are important in protecting medical staff from exposure to pathogens during surgery, especially viruses such as hepatitis B and the human immunodeficiency virus. We have studied the incidence and circumstances of surgical glove perforation using a sensitive electronic device. The glove perforation rate during elective general surgery was compared with that seen during an anastomosis workshop, where surgical trainees operated in a laboratory setting. A total of 220 gloves were tested for perforations pre- and postoperatively during general elective surgical procedures. During the surgical training workshop 72 gloves were tested. Fifty-two gloves (24%) were perforated during surgical procedures. Among surgeons, consultants had a significantly lower perforation rate than trainees (26% vs 46%, P < 0.05, chi 2), that for assistants was much lower (9%). The perforation rate for scrub nurses was surprisingly high at 22%. Glove perforation among trainees was significantly lower during workshop procedures than at elective surgery (17% vs 46%, P < 0.05, chi 2), probably because glove perforation occurs commonly at wound closure. Glove perforation remains very common, particularly among surgical trainees. Glove perforation should be reduced by teaching better techniques, especially 'no-touch', particularly for wound closure.

Operative and nonoperative risks in the cardiac patient.

Four hundred and sixteen patients with documented arteriosclerotic heart disease (ASHD) underwent 424 diagnostic and therapeutic surgical procedures during the year 1970 at the Henry Ford Hospital. They were classified according to the specific clinical manifestation of their cardiac abnormality. Patients with a history of old, well-compensated myocardial infarction, and those with cardiac arrhythmia, bundle-branch block, congestive heart failure and A-V block (pacemaker-protected) but no evidence of previous myocardial infarction fared almost as well as subjects of the same age without cardiac disease, and were considered to run the lowest operative risk. Patients with angina, especially if there was a history of infarction, were an intermediate risk in terms of complications and mortality. Patients with a history of previous infarction complicated at the time of the surgical procedure by arrhythmia, A-V block, bundle-branch block, or congestive heart failure were in the "highest risk" category. A severe A-V block indicated the need for insertion of a "prophylactic" pacemaker before any attempt at a diagnostic or therapeutic procedure. No patient with clinical or electrocardiographic evidence of a recent infarction (less than three months' duration) should undergo any elective surgical procedure under any form of anesthesia unless the surgeon is prepared for a high mortality rate that may approach 90 percent. In contrast, the patient with old, well-compensated myocardial infarction and no evidence of dysrhythmia, block or congestive failure can tolerate even a major surgical operation under any form of anesthesia extremely well.

The rational use of homologous blood in elective surgery.

The supply of homologous blood in Australia is limited, but the demand for blood and blood products is steadily increasing. Elective surgery is a major part of this demand. In many institutions the blood ordering practices for elective surgery have been haphazard. This study was undertaken to document current patterns of blood use in a major city teaching hospital. A retrospective analysis of blood ordering and transfusion for elective surgical procedures was carried out over a 12 month period. As in several previous studies, an inefficient use of blood was demonstrated. Possible strategies to rationalize the use of blood in elective surgery have been proposed. These include the use of a 'group and screen' procedure instead of a full cross-match when transfusion is unlikely to be necessary, and ordering according to a 'maximum blood order schedule' when transfusion is usually required for a procedure.

[Peridiverticulitis of the colon: confrontation of pre- and postoperative diagnosis (author's transl)].

The authors report their experience with the surgical management of the peridiverticulitis coli (60 cases). It is frequently uneasy to have an accurate pre- and peroperative diagnosis of the nature and the grade of severity of the illness. So, the indication for surgery, the choice of the procedure, and the evaluation of the results are somewhat subjective. The microscopical study of the resected colons give objective data about the status of the bowel. Our pathological findings have shown major inflammatory lesions in the colons which were resected in emergency, in the cases operated upon for stenoses and fistula. On the other hand, when patients underwent an elective surgical procedure, after a primary conservative (medical or surgical) treatment, the inflammation could be absent. The risks of leaving in place some of these colons seem to be small.

[Acupuncture analgesia in China (author's transl)].

As part of an agreement between the Governments of the People's Republic of China and Canada, 10 Canadian Anaesthetists visited China for six weeks during April and May 1974. The delegation observed 87 surgical operations and 19 dental procedures conducted under acupuncture analgesia in 17 large hospital in Peking, Schichiachuang, Nanking, Shanghai and Canton. In this report, observations on acupuncture analgesia made during this visit are presented as well as information obtained in group discussions with Chinese physicians. In the author's opinion, the technique was successful in about 80% of the cases seen; these patients were awake during surgery without visible distress and exhibited a remarkable degree of analgesia immediately after surgery. However, in China, acupuncture analgesia is still considered in the experimental stage and only used in a limited number of standardized, elective surgical procedures, where confidence and the success of this technique have been established. For the successful use of this technique, patient and surgeon must co-operate fully. Acupuncture analgesia poses considerable limitations on the surgeon and requires careful surgical technique; the patient's co-operation must be assured by a suitable preparation. It appears, that acupuncture analgesia should be seen as an alternative to local anaesthesia rather than general anaesthesia; the latter is only used to a limited extent in China. In our present anaesthetic practice, acupuncture would appear to be of only very limited use, however, a further study of this phenomenon should contribute to our knowledge of the function of the nervous system.

Foreign bodies in the hand in children.

Foreign bodies in the hand in children are best managed when the surgeon has a well-organized approach to the total problem. The procedure of restraining a child, infiltrating the wound with local anesthetic, and probing the wound deep in the hand on the day of injury to remove the foreign body is discouraged. A detailed examination of the hand for cut tendons and nerves should be done. The initial treatment should be thorough cleaning of the skin, application of compresses wet with Bunnell's hand solution, systemic antibiotics, and tetanus prophylaxis. The foreign body is removed, as an elective surgical procedure, only if there is evidence of infection or persistent pain or both. Six weeks after all evidence of infection has cleared appropriate reconstructive procedures can be done.

Mode of failure of the Mitroflow pericardial valve.

A consecutive series of 188 Mitroflow pericardial bioprostheses were inserted in 166 patients between 1st January 1983 and 31st December 1985. Twenty-two valves had to be removed from 16 patients after a mean follow up period of 78 months (range 58-92 months) for aortic, 73 months (65-79 months) for mitral and 78 months (48-103 months) for double valve replacements. All but one reoperations for primary tissue failure were carried out as elective surgical procedures. The most important cause of failure was collagen degeneration, seen in all explanted valves. The areas of degeneration were the major sites of origin of calcification, which was seen in 11 valves (50%). Ten valves (45%) showed features suggestive of lipid infiltration, extensive fatty acid deposition being identified in one and a typical atheromatous reaction in another. In contrast to the Ionescu-Shiley valve, the mode of failure was tear originating at the top of the commissure, associated with major structural changes in the tissue. Excessive pannus ingrowth was observed in 11 valves (50%). The universal presence of tissue degeneration in the glutaraldehyde treated pericardial leaflets of the Mitroflow bioprostheses explanted and examined in this study questions the adequacy of the methods employed in the harvesting and/or processing and/or preservation of this valve. We have, therefore, discontinued using the Mitroflow bioprosthesis. However, the slow deterioration of the Mitroflow bioprosthesis permits elective reoperation; preventive removal of functioning valves is therefore not indicated.
