Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
Morphometry and Morphology of Extracranial Part of Facial Nerve – A Cadaveric Study
Introduction: Identification of the extracranial part of facial nerve with respect to bony landmarks is important to avoid injury to it. Purpose: To measure the length of the facial nerve trunk and its divisions and to measure the distance of the nerve trunk with the mastoid process and atlas. The variations in the divisions and branches were also noted. Methods: Twenty hemi-faces were dissected. The facial nerve was identified at the stylomastoid foramen and dissected meticulously through the parotid gland. The divisions and branches were identified and traced. The trunk was measured from the stylomastoid foramen to its point of bifurcation. The length of the two divisions were measured up to their branching. The distance from the nerve trunk to the mastoid process and atlas were measured. Results: Mean length of facial nerve trunk in centimetres was 1.380±0.082, length of upper division was 0.820±0.108 and length of lower division was 0.890±0.090. The mean distance in centimetres between the facial nerve trunk and mastoid process tip was 1.300±0.089 and the distance between facial nerve trunk and transverse process of atlas was 1.645±0.108. Conclusion: The above data may help in minimising injury to the facial nerve
Variation in the formation of the retromandibular and the external jugular veins with embryological overview: A case report
Awareness of the formation and termination of the head & neck's superficial vein, such as jugular veins, are imperative for anatomists, surgeons, and radiologists during interventional procedures. We report an uncommon variation in the formation of the retromandibular vein and external jugular vein (EJV) in an embalmed male cadaver's right side. The joining of the facial vein and superficial temporal vein within the parotid gland formed the retromandibular vein (RMV). The anterior division joined with the submental vein forming an anomalous venous trunk. The anomalous vein united with the EJV forming a common trunk in the lower third of the neck and terminated into the subclavian vein. We compared the available literature and justified the embryological development of this rare variation
Variant Musculo-tendinous Slip between Teres major and Triceps brachii
A variation of the muscles of the scapular region is a very rare finding. During the routine dissection for the undergraduates, a variant short musculo-tendinous slip in between the teres major and the long head of triceps brachii muscles was seen. This slip could cause compression of the underlying brachial vessels and the cords of brachial plexus. Therefore this type of variation is worthy of being noted by the surgeons
ansa cervicalis: anatomical variation
The ansa cervicalis is a loop of nerves that is usually formed by the union of ventral rami of spinal nerves C1, C2, and C3. It is located in the carotid triangle of the neck, lying superficial to the carotid sheath. During routine dissection, unilateral variation of the ansa cervicalis was observed. The superior root, arising from hypoglossal nerve, was initially bifurcated and later united to form a single superior root. IN addition, the inferior root consisted of fibres arising from the spinal accessory nerve, C1, C2 and C3 spinal nerves that joined separately. Fibres from the spinal accessory and C1 joined to form a single root. Thus, a ‘triple form’ of ansa cervicalis was observed. An interconnection was observed between the C2 and C3 fibres. Knowledge of such anatomical variations is important for surgery, clinical intervention or trauma involving the carotid triangle or the structures within or deep to this region
Palmaris Longus Muscle in the South Indian Population – A Cadaveric Study
Introduction: Palmaris longus, one of the superficial flexor muscles of the anterior compartment of the forearm is the most variable muscle of the upper limb. Purpose: To note the variations of palmaris longus for tendon grafts. Methods: Forty formalin-fixed upper limb specimens of South Indian population were dissected to note the variations of Palmaris longus muscle. Results: Out of the forty upper limb specimens, two variants of the palmaris longus were noted. In one specimen, a reversed palmaris longus was noted. It had a long tendinous origin with a muscle belly and a short flat tendon at insertion. The tendon inserted partly into the flexor retinaculum and partly into palmar aponeurosis. In another specimen, apart from the normal palmaris longus muscle, an additional smaller muscle was noted. It was the Palmaris profundus. This muscle took origin in the form of a tendon from the middle of the shaft of the radius, continued as a muscle belly and then terminated as a tendon which later inserted into the flexor retinaculum, close to the tendon of palmaris longus muscle. At its insertion, the superficial palmar branch of radial artery hooked it. The anterior interosseous nerve supplied the Palmaris profundus. Conclusion: These variations are worthy to be noted for tendon grafts
