“…Postoperative pain was associated with postoperative hypoxaemia. Compared to patients with severe pain, patients with mild and no pain were 82% and 88% less likely to experience postoperative hypoxaemia, respectively ( 34 ). Peripheral tissue oxygen saturation was reduced in response to pain, which may account for the association between severe pain and hypoxemia ( 35 ).…”

ObjectivesTo explore the risk factors associated with postoperative hypoxaemia in elderly patients who have recovered from coronavirus disease (COVID-19) and underwent hip fracture surgery in the short term.DesignMulticentre retrospective study.SettingThe study was performed in three first 3A-grade hospitals in China.ParticipantsA sequential sampling method was applied to select study participants. Medical records of 392 patients aged ≥65 years who had recovered from COVID-19 and underwent hip fracture surgery at three hospitals in China between 1 November, 2022, and 15 February, 2023, were reviewed.InterventionsPatients were assigned to hypoxaemia or non-hypoxaemia groups, according to whether hypoxaemia occurred after surgery. Univariate and multivariate logistic regression analyses were used to identify independent risk factors for postoperative hypoxaemia.ResultsThe incidence of postoperative hypoxaemia was 38.01%. Statistically significant differences were found between the two groups in terms of age, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, presence of expectoration symptoms, preoperative hypoxaemia, chronic obstructive pulmonary disease, pulmonary inflammation, time between recovery from COVID-19 and surgery, anaesthetic mode, surgical procedure, intraoperative blood loss, intraoperative infusion, duration of surgery, and length of hospital stay (p < 0.05). Furthermore, patients with BMI ≥28.0 kg/m2, expectoration symptoms, presence of preoperative hypoxaemia, ASA classification III, time between recovery from COVID-19 and surgery ≤2 weeks, and general anaesthesia were potential risk factors for postoperative hypoxaemia.ConclusionObesity, expectoration symptoms, preoperative hypoxaemia, ASA classification III, time between recovery from COVID-19 and surgery ≤2 weeks, and general anaesthesia were potential risk factors for postoperative hypoxaemia in elderly patients who recovered from COVID-19 and underwent hip fracture surgery in the short term.

“…Postoperative hypoxia is a common challenge faced by surgeons. The earlier data suggested its incidence to be around 55% [9], but with the introduction of new and short-acting anesthetic drugs, minimally invasive surgical procedures, enhanced postoperative care, and the advent of day-care surgery, the incidence has fallen down to just around 20% in elective surgeries [10][11]. A catena of studies has highlighted the causes of postoperative hypoxia.…”

Postoperative hypoxia is a challenge for surgeons. With the advent of better anesthesia and minimal access surgical techniques, the incidence of postoperative hypoxia in elective cases has decreased. However, the incidence in life-saving emergency procedures still poses a possible threat, and cases seem under-reported. We report a series of five cases of postoperative hypoxia after laparotomy. These cases comprise mesenteric laceration, proximal jejunal perforation, perforated duodenal ulcer, abdominal tuberculosis, and fall from height. Despite different etiologies, they landed up with the complication of postoperative hypoxia, which was attributable to the type of procedure they underwent and not the indication of the procedure itself. Thus, they form an interesting collection of post-laparotomy hypoxia cases. We present them with a compilation of probable causes of postoperative hypoxia in such cases.Postoperative hypoxia presents a diagnostic challenge and requires timely suspicion, prompt intervention to eliminate the cause, and good postoperative care. The major causes include incomplete lung re-expansion, pain-induced restriction in chest-wall/diaphragm mobility, prolonged surgery, a complication of preexisting lung disease, residual effects of some drugs, and iatrogenic causes. We, therefore, recommend the use of postoperative oxygen support and diligent monitoring of vitals in all cases of laparotomy, allowing prompt and timely patient management. Future studies are warranted to explore the prevalence and possible causes of post-laparotomy hypoxia.

“…No significant differences were found in this study between groups regarding potassium. Unfortunately, no follow-up testing of laboratory parameters occurred, but it is conceivable that cellular damage due to acidosis or hypoxia could lead to an increase in potassium levels [33], and deviations in the ECG may arise as a result of this. Finally, this study showed a negative correlation between the duration of the T wave and the internal body temperature in the eutocia group, while a negative correlation between the respiratory frequency and the QT interval was found in the dystocia group.…”

Comparative study of electrocardiographic parameters in calves born after eutocia versus dystocia

et al. 2022

Background and Aim: The mortality rate of perinatal calves is high, particularly in dystocia cases. Besides detectable conditions such as trauma or amniotic fluid aspiration, the potential salience of cardiological diseases in neonatal bovine deaths has received little attention. This study aimed to compare the electrocardiographic parameters of calves born under conditions of dystocia and eutocia. Materials and Methods: Electrocardiographic, clinical, and laboratory diagnostic examinations were performed during the first 5 days of life on 40 calves. Of them, 20 calves were born under conditions of dystocia and 20 of eutocia. Results: Electrocardiograms (ECGs) did not show detectable arrhythmias in all calves. Both groups exhibited tachycardia on their first ECGs. The QT and ST interval durations developed differently over time in both groups, suggesting that these may be related to conditions of birth. Conclusion: The electrocardiographic differences between calves born of dystocia and eutocia could be a factor in the increased mortality rate of calves born of dystocia.
