Anesthesiology; July 2021; 135(1):31–56.

PMID: 34046679 DOI: 10.1097/ALN.0000000000003808

  • Anesthesia clinical practice guidelines make evidence-based recommendations intended to optimize patient outcomes. The extent to which these recommendations are supported by high-quality evidence is not known.
What This Article Tells Us
  • In a systematic review of 2,280 recommendations in 60 guidelines published by major North American and European societies, half of the recommendations were supported by a low level of evidence.
  • The proportion of recommendations supported by a high level of evidence did not increase between 2010 and 2020.

Postoperative Pulmonary Complications’ Association with Sugammadex versus Neostigmine: A Retrospective Registry Analysis 

Gen Li, M Stat., M Chem; Robert E Freundlich, MD, MS, MSCI; Rajnish K Gupta, MD;  Christina J Hayhurst, MD; Chi H Le, BS; Barbara J Martin, RN, MBA; Matthew S Shotwell, PhD; Jonathan P Wanderer, MD, M Phil, FASA, FAMIA

Anesthesiology; June 2021; 134(6):862-873

PMID: 33730169 DOI: 10.1097/aln.0000000000003735

  • Compared with neostigmine, sugammadex demonstrates improved rates of residual neuromuscular blockade
  • There are limited data using validated surgical registry outcome data to evaluate the association between use of sugammadex and reduced pulmonary complications
What This Article Tells Us
  • At a medical center that implemented a complete switch from neostigmine to sugammadex, a statistically significant difference in pulmonary complication rates was not observed between 7,800 general surgery patients receiving neostigmine versus 2,691 general surgery patients receiving sugammadex
  • Although rates of pulmonary complication after general surgery are decreasing, some of this change may be attributable to temporal trends in practice unrelated to the use of neostigmine versus sugammadex

Intraoperative Blood Pressure Monitoring in Obese Patients: Arterial Catheter, Finger Cuff, and Oscillometry

Roman Schumann, MD; Agnes S Meidert, MD; Iwona Bonney, PhD; Christos Koutentis, MB, ChB, MS; Wilbert Wesselink, PhD.; Karim Kouz, MD; Bernd Saugel, MD

Anesthesiology; February 2021: 134(2):179–188

PMID: 33326001 DOI: 10.1097/aln.0000000000003636

  • Optimal blood pressure monitoring in obese surgical patients remains unknown because multiple invasive and noninvasive monitoring methods are available with little understanding of agreement between different methods.
 What This Article Tells Us
  • In a study of 90 obese patients having bariatric surgery, the agreement between finger cuff and intraarterial measurements was better than the agreement between oscillometric and intraarterial measurements for mean arterial and diastolic blood pressure, but not systolic blood pressure. Forearm oscillometry demonstrated better measurement performance than upper arm or lower leg oscillometry.

Management of Difficult Tracheal Intubation: A Closed Claims Analysis 

Aaron M Joffe, DO; Michael F Aziz, MD; Karen L Posner, PhD; Laura V Duggan, MD, FRCPC; Shawn L Mincer, MSW; Karen B. Domino, MD, MPH

Anesthesiology; October 2019; 131(4):818–829

PMID: 31584884 DOI: 10.1097/aln.0000000000002815

  • Difficult or failed intubation is a major contributor to morbidity for patients and liability for anesthesiologists.
  • Updated difficult airway management guidelines and incorporation of new airway devices into practice may have affected patient outcomes.
What This Article Tells Us
  • This article compared recent malpractice claims related to difficult tracheal intubation to historic claims using the Anesthesia Closed Claims Project database.
  • Outcomes remained poor in recent malpractice claims related to difficult tracheal intubation. The number of claims during the induction phase of anesthesia in this report is comparable with the previous report of 1993 to 1999, but outcomes are poorer.
  • Inadequate airway planning and judgment errors were contributors to patient harm. Almost three fourths exhibited judgment failures, which were more common in elective and urgent intubation procedures than emergency tracheal intubations.
  • Delay in surgical airway initiation during “can’t intubate, can’t oxygenate” emergencies remains an issue in airway management.

Oshri Barel, MD, MHA, FRANZCOG; Elad Preuss, MD; Natan Stolovitch, MD; Shiri Weinberg, MD; Eran Barzilay, MD, PhD; Moty Pansky, MD

J Minim Invasive Gynecol; April 2021;28(4):865-871

PMID: 32798723 DOI: 10.1016/j.jmig.2020.08.003 

  • Pain is the main cause of office hysteroscopy. Adding a local anesthetic to distension medium in the office diagnostic hysteroscopy using the vaginoscopic “no touch” approach (avoiding speculum and tenaculum) may reduce pain.
  • Oher modalities such as injection of intrauterine, cervical local anesthetic is painful and adds time to the procedure.
What This Article Tells Us
  • Randomized double blind placebo-controlled study of 100 patients. 10 ml of lidocaine 2% added to 1000ml of saline solution used as distension medium for hysteroscopy in the control group of 50 patients and 1000ml saline solution for the control
  • The lidocaine group has a lower VAS pain score (an average rise of 1.9 vs. 2.9 in the control group) without the added time to procedure or side effects.

E Jackson; N Kapp

BJOG; October 2020; 127(11):1348-1357

PMID: 32162427 DOI: 10.1111/1471-0528.16212

  • Pain control for termination of pregnancy is dependent on practitioners and the available guidelines do not specify optimal strategies.
  • This study looked at articles from PubMed, Cochrane and Embase databases, and US National Library of Medicine clinical trials registry from inception to end of June 2019. A total of 11 studies comparing pain management strategies for induced medical (7 studies) or surgical (4 studies) termination of pregnancy between 13 and 24 weeks of gestation were included.
What This Article Tells Us 
  • 10% of women who need termination of pregnancy globally have gestation of > 13 weeks. Termination of pregnancy at later gestational age increases the pain intensity and length of time.
  • Regional analgesia and NSAIDs decrease second trimester medical termination of pregnancy pain
  • General anesthesia and deep IV sedation alleviated surgical termination of pregnancy pain. Nitrous oxide was ineffective when compared to moderate sedation using IV fentanyl and midazolam

Suzanne J Dedden; Peggy MAJ Geomini; Judith AF Huirne; Marlies Y Bongers

Eur J Obstet Gynecol Reprod Biol; July 2017; 216:212-223

PMID: 28810192 DOI: 10.1016/j.ejogrb.2017.07.015

  • Vaginal and laparoscopic hysterectomy patients are usually admitted overnight unlike other gynecological procedures such as laparoscopic sterilization and oophorectomies which are same day discharge.
  • Review of literature to identify complications, risk factors for admission, financial consequences, and patient satisfaction for same day discharge after a vaginal or laparoscopic hysterectomy.
What This Article Tells Us
  • 27 articles from PubMed, UptoDate, Embase, Cochrane and CINAHL database from inception until July 16, 2016
  • Overall re-admission rate varies from 0.73-4%. Main reasons for admission were pain, nausea, urinary retention, infection, and anemia. Preoperative factors that negatively influence same day discharge are increased age, medical co-morbidities, concomitant procedures, and surgeon’s preference.
  • Same day discharge after laparoscopic and vaginal hysterectomy can be feasible in pre-selected, and healthy patients.It is associated with low admission rate, low complication rate, reduced hospital costs, and high patient satisfaction.

The Value of Routine Preoperative Medical Testing Before Cataract Surgery

Oliver D Schein, MD, MPH; Joanne Katz, ScD; Eric B Bass, MD, MPH; James M Thielsch, PhD; Lisa H Lubomski, PhD; Marc A Feldman, MD, MPH; Brent G Petty, MD; and Earl P Steinberg, MD, MPP for the Study of Medical Testing for Cataract Surgery

New England Journal of Medicine; January 20, 2000; 342(3):168-175

PMID: 10639542 DOI: 10.1056/NEJM200001203420304

Why this study was performed

  • Cataract surgery is the most common operation performed in the elderly population, and the morbidity and mortality of this procedure is extremely low.
  • The utility of preoperative testing in cataract surgery is uncertain and many physicians feel that preoperative testing and examination is required.
  • The cost of preoperative testing to Medicare is quite high.

What this article tells us:

  • Adverse medical events during and immediately after cataract surgery as well as cancellations and postponements are independent of preoperative routine testing.
  • This is irrespective of severity of risk class or coexisting illnesses.
  • Routine medical testing before cataract surgery doesn’t measurably increase the safety of the surgery. 

Preoperative Medical Testing in Medicare Patients Undergoing Cataract Surgery

New England Journal of Medicine; April 16, 2015; 372(16): 1530-8

PMID: 25875258 DOI: 10.1056/NEJMsa1410846

Why this study was performed:

  • Cataract surgery has been shown to be a very safe procedure and routine preoperative testing has been shown to be unnecessary.
  • This study was performed to assess provider adherence to the previously-published guidelines recommending that no preoperative testing is required for routine cataract surgery.

What this article tells us:

  • Over 50% of patients undergoing cataract surgery underwent at least one preoperative test despite evidence against its benefit, resulting in likely unnecessary Medicare expenses.
  • There is no difference in the amount of testing performed compared to 20 years prior to the study.
  • Publishing evidence-based guidelines alone does not alter behavior and the physician care team is the primary determinant of whether testing is performed. 

Does Intraoperative Ketorolac Increase Bleeding in Oculoplastic Surgery?

Minwook Chang, MD. PhD; Adam Gould, MD; Zvi Gur, MD; Ortal Buhbut, MD; Hetal Hosalkar, MD; Catherine Y. Liu, MD, PhD; Bobby S Korn, MD, PhD, FACS and Don O Kikkawa, MD, FACS

Ophthalmic Plast Reconstr Surg; Jul/Aug 2020; 36(4): 355-358

PMID: 31809483 DOI: 10.1097/IOP.0000000000001549

Why this study was performed:

  • To report adverse hemorrhagic outcomes in patients who received intravenous ketorolac during oculoplastic surgery.

What this article tells us:

  • Interoperative ketorolac administration does not increase the risk of postoperative bleeding in oculoplastic surgical procedures.
  • This may be a useful adjunct to multimodal analgesia and thus decrease the use of narcotics. 

Anesthesia Recovery After Ophthalmologic Surgery at an Ambulatory Surgery Center

Kyle M Russell, RN; Mary E Warner, MD; Jay C Erie, MD; Chandralekha S Kruthiventi, MD; Juraj Sprung, MD, PhD and Toby N Weingarten, MD

Journal of Cataract & Refractive Surgery; June 2019; 45(6): 823-829

PMID: 31146933 DOI: 10.1016/j.jcrs.2019.01.017

Why this study was performed:

  • To examine anesthesia recovery duration after ophthalmologic procedures performed at an ambulatory surgery center.

What this study tells us:

  • Duration of recovery after ophthalmologic surgery in an ambulatory surgery center is associated primarily with procedure type with longest recoveries for orbitotomy and strabismus procedures; shortest for cataract surgery.
  • Intraoperative fentanyl use, severe postoperative pain and postoperative opioid requirements are associated with longer recoveries.
